Effect of metalloproteinase inhibitor on corneal cytokine expression after alkali injury. (1/440)

PURPOSE: Interleukin (IL)-1alpha and IL-6 levels in the cornea are greatly elevated during the early stages after an alkali burn in mice. The authors investigated the effect of synthetic inhibitor of matrix metalloproteinase (SIMP) on the expression of inflammatory cytokines in alkali-burned murine corneas and evaluated the clinical appearance of the eyes. METHODS: After 0.5N NaOH-alkali burns to 400 corneas of ICR mice, 200 received 400 microg/ml of SIMP topically 4 times a day while 200 corneas were similarly treated with vehicle only. At days 4, 7 and 14 after injury, each cornea was assigned a clinical score for corneal opacity, corneal epithelial defect, hyphema and cataract. Extracts of injured corneas in each group were then assayed for cytokine production using ELISA systems for IL-1alpha, IL-1beta, IL-6 and tumor necrosis factor-alpha (TNF-alpha). RESULTS: The levels of IL-1alpha, IL-1beta and IL-6 were significantly lower in the SIMP-treated group than in the vehicle-treated group 7 days after the burn. However, levels of these cytokines were similar in the SIMP and non-SIMP groups at days 4 and 14. Levels of TNF-alpha did not differ between both groups at any postinjury time. In the SIMP-treated corneas, there was less opacification and hyphema formation and epithelial regeneration was faster. CONCLUSIONS: Topical application of SIMP in alkali-burned murine corneas reduced the expression of IL-1alpha, IL-1beta, and IL-6 and lessened the severity of the injury.  (+info)

The effects of ouabain and potassium on peritoneal fluid and solute transport characteristics. (2/440)

BACKGROUND: We reported anomalous transport characteristics of potassium during experimental peritoneal dialysis in rats and suggested that mechanisms of peritoneal potassium transport could be other than simple passive transport. Intracellular transport of potassium in cultured human mesothelial cells was reported to be regulated by three different pathways, such as channels blocked by ouabain, channels blocked by furosemide, and other. OBJECTIVE: To investigate the effect of ouabain on peritoneal potassium and water transport characteristics. METHODS: A single 4-hour peritoneal dwell was performed in 28 Sprague-Dawley rats. To minimize the diffusive transport of potassium, 4.5 mmol/L of KCl was added into conventional dialysis solution with 3.86% glucose [acidic peritoneal dialysis solution (APD)]. To evaluate the effect of the pH of dialysis solution on the transport of potassium and water, 4 mmol/L of NaOH was added into the potassium-containing study solutions [neutral peritoneal dialysis solution (NPD)]. To evaluate the effect of a potassium channel blocker on peritoneal potassium transport ATPase sensitive Na+-K+-transport inhibitor, ouabain (10(-5) mmol/L) was added to dialysis solutions immediately before the dwell study in eight rats with APD (APD-O) and six rats with NPD (NPD-O). Ouabain was not added in eight and six rats with APD and NPD (APD-C and NPD-C, respectively). They were used as control. Infusion volume was 30 mL. The intraperitoneal volume (V(D)) was estimated by using a volume marker dilution method with corrections for the elimination of volume marker, radioiodinated human serum albumin (RISA), from the peritoneal cavity (K(E)). The diffusive mass transport coefficient (K(BD)) and sieving coefficient (S) were estimated using the modified Babb-Randerson-Farrell model. RESULTS: V(D) was significantly higher (p < 0.05 from 90 min to 240 min) and K(E) (0.027+/-0.018 mL/min for APD-O, 0.026+/-0.017 mL/min for NPD-O, and 0.030+/-0.022 mL/min for NPD-C, vs 0.058+/-0.030 mL/min for APD-C, p < 0.05 for each) significantly lower during dialysis with APD-O, NPD-O, and NPD-C than with APD-C. The intraperitoneal glucose expressed as a percentage of the initial amount was significantly higher with APD-O, NPD-C, and NPD-O than with APD-C (p < 0.05 from 90 min to 240 min). K(BD) for sodium was higher during dialysis with ouabain than without ouabain, while K(BD) for urea, glucose, and potassium, and S for urea, glucose, sodium, and potassium did not differ between the four groups. CONCLUSIONS: The physiologic potassium concentration in neutral dialysis solutions and the use of ouabain decreased the intraperitoneal fluid absorption. The diffusive transport coefficient and sieving coefficient for potassium did not differ, while the diffusive transport coefficient for sodium increased during use of ouabain.  (+info)

The molecular basis of the solution properties of hyaluronan investigated by confocal fluorescence recovery after photobleaching. (3/440)

Hyaluronan (HA) is a highly hydrated polyanion, which is a network-forming and space-filling component in the extracellular matrix of animal tissues. Confocal fluorescence recovery after photobleaching (confocal-FRAP) was used to investigate intramolecular hydrogen bonding and electrostatic interactions in hyaluronan solutions. Self and tracer lateral diffusion coefficients within hyaluronan solutions were measured over a wide range of concentrations (c), with varying electrolyte and at neutral and alkaline pH. The free diffusion coefficient of fluoresceinamine-labeled HA of 500 kDa in PBS was 7.9 x 10(-8) cm(2) s(-1) and of 830 kDa HA was 5.6 x 10(-8) cm(2) s(-1). Reductions in self- and tracer-diffusion with c followed a stretched exponential model. Electrolyte-induced polyanion coil contraction and destiffening resulted in a 2.8-fold increase in self-diffusion between 0 and 100 mM NaCl. Disruption of hydrogen bonds by strong alkali (0.5 M NaOH) resulted in further larger increases in self- and tracer-diffusion coefficients, consistent with a more dynamic and permeable network. Concentrated hyaluronan solution properties were attributed to hydrodynamic and entanglement interactions between domains. There was no evidence of chain-chain associations. At physiological electrolyte concentration and pH, the greatest contribution to the intrinsic stiffness of hyaluronan appeared to be due to hydrogen bonds between adjacent saccharides.  (+info)

Recovery of mycobacteria from patients with cystic fibrosis. (4/440)

Despite decontamination, overgrowth by pseudomonads renders cultural isolation of mycobacteria from respiratory specimens of patients with cystic fibrosis (CF) difficult or impossible. We performed a prospective study by comparing levels of reduction of overgrowth and recovery of mycobacteria using either pretreatment with N-acetyl-L-cysteine (NALC)-NaOH alone or pretreatment with NALC-NaOH and then with oxalic acid. From 406 specimens of 148 CF patients, 11 specimens were positive for mycobacteria, 5 of which grew mycobacteria after decontamination by either procedure. Three specimens grew mycobacteria only after decontamination with NALC-NaOH, whereas three specimens grew mycobacteria only after treatment with NALC-NaOH followed by oxalic acid but were overgrown after decontamination with NALC-NaOH. Thus, inactivation of mycobacteria by the more aggressive oxalic acid treatment offsets its beneficial effect of reducing the proportion of cultures overgrown with microorganisms other than mycobacteria.  (+info)

Association of bacteriochlorophyll a with the CsmA protein in chlorosomes of the photosynthetic green filamentous bacterium Chloroflexus aurantiacus. (5/440)

The protein assumed to be associated with bacteriochlorophyll (BChl) a in chlorosomes from the photosynthetic green filamentous bacterium Chloroflexus aurantiacus was investigated by alkaline treatment, proteolytic digestion and a new treatment using 1-hexanol, sodium cholate and Triton X-100. Upon alkaline treatment, only the 5.7 kDa CsmA protein was removed from the chlorosomes among six proteins detected by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis, concomitantly with the disappearance of BChl a absorption at 795 nm. Trypsin treatment removed two proteins with molecular masses of 11 and 18 kDa (CsmN and CmsM), whereas the spectral properties of BChl a and BChl c were not changed. By the new hexanol-detergent (HD) treatment, most BChl c and all of the detected proteins except CsmA were removed from the chlorosomes without changing the BChl a spectral properties. Subsequent proteinase K treatment of these HD-treated chlorosomes caused digestion of CsmA and a simultaneous decrease of the BChl a absorption band. Based on these results, we suggest that CsmA is associated with BChl a in the chlorosomes. This suggestion was supported by the measured stoichiometric ratio of BChl a to CsmA in isolated chlorosomes, which was estimated to be between 1.2 and 2.7 by amino acid analysis of the SDS-PAGE-resolved protein bands.  (+info)

The structure of the carbohydrate backbone of core-lipid A region ofthe lipopolysaccharides from Proteus mirabilis wild-type strain S1959 (serotype O3) and its Ra mutant R110/1959. (6/440)

The following structure of core-lipid A region of the lipopolysaccharide (LPS) from Proteus mirabilis strain 1959 (serotype O3) and its rough mutant R110/1959 (Proteus type II core) was determined using NMR and chemical analysis of the core oligosaccharide, obtained by mild acid hydrolysis of LPS, and of the products of alkaline deacylation of the LPS: Incomplete substitutions are indicated by italics.

The differences with the previously reported structures are discussed.  (+info)

A comparison of sodium hydroxide and sodium sulfide digestion of mouse hair in the recovery of radioactivity following systemic administration of [3H]-nicotine and [3H]-flunitrazepam. (7/440)

Pigmented (C57BI) and nonpigmented (balb/c) mice, 25 days of age, were treated intraperitoneally with [3H]-nicotine (4 mg/kg, 555 dpm/ng) or [3H]-flunitrazepam (1 mg/kg, 2200 dpm/ng) daily for three days. After 21 days, shaved back hair was digested at 37 degrees C for 24 h with either 1 M sodium hydroxide or 1 M sodium sulfide. With both drugs, sodium sulfide extraction removed the same amount of radioactivity as sodium hydroxide from nonpigmented hair. However, sodium sulfide removed significantly more radioactivity from pigmented hair than did sodium hydroxide. In pigmented hair, sodium sulfide solubilized 35% and 74% of the flunitrazepam- and nicotine-associated radioactivity, respectively. Of this, 12% and 43%, respectively, could be partitioned into ethyl acetate. Microscopic examination of residual pellets after digestion demonstrated a more thorough dissolution of the hair shaft with sodium sulfide with only melanosomes remaining. The results demonstrate the significant interaction of flunitrazepam and nicotine with melanins and the utility of sodium sulfide in increasing drug recovery.  (+info)

Compound A does not accumulate during closed circuit sevoflurane anaesthesia with the Physioflex. (8/440)

We have investigated inspiratory and end-tidal gas composition during sevoflurane anaesthesia in a closed circle system with continuous gas flow (70 litre min-1, Physioflex) to determine possible accumulation of sevoflurane degradation products. During five abdominal operations in adults lasting more than 2 h, anaesthesia was maintained with an end-tidal concentration of 2% sevoflurane in 40% oxygen-air. The circle included an absorbing canister filled with 1 litre of fresh soda lime. Samples were obtained at the end of an expiration from the tracheal tube and from the inspiratory limb before, and at selected times after, addition of sevoflurane. The temperature of soda lime was 24.7 +/- 0.7 degrees C at the beginning and reached a maximum of 31.2 +/- 1.0 degrees C after 20-30 min, followed by a plateau. Inspiratory compound A (CH2F-O-C(= CF2)(CF3)) 3-8 ppm was detected after 10 min, but did not accumulate in the circle over 2 h without flushing. Expired concentrations were consistently lower with 1.5-3 ppm signalling absorption by patients. Calculated total amounts absorbed over 2 h varied between 2.0 and 7.2 ppm h. Other degradation products such as compound B or methanol were not detected. In summary, we did not detect sevoflurane metabolites with soda lime in significant amounts during closed circle anaesthesia with the Physioflex. The observed concentrations of compound A were below the threshold of nephrotoxicity in rats by a factor of more than 20.  (+info)

Two of the more common household products containing sodium hydroxide are drain cleaners and oven cleaners. When most pipes are clogged it is with a combination of fats and grease. Cleaners that contain sodium hydroxide (either as a solid or already dissolved in water) convert the fats to soap, which dissolves in water. In addition, when sodium hydroxide dissolves in water a great deal of heat is given off. This heat helps to melt the clog. Sodium hydroxide is very damaging to human tissue (especially eyes). If a large amount of solid drain cleaner is added to a clogged drain, the heat produced can actually boil the water, leading to a splash in the eyes of a solution caustic enough to cause blindness. Some drain cleaners also contain small pieces of aluminum metal. Aluminum reacts with sodium hydroxide in water to produce hydrogen gas. The bubbles of hydrogen gas help to agitate the mixture, helping to dislodge the clog.. Oven cleaners work by converting built up grease (fats and oils) into ...

Sodium hydroxide - WikipediaSodium hydroxide - Wikipedia
Sodium hydroxide is a popular strong base used in industry. Around 56% of sodium hydroxide produced is used by industry, 25% of which is used in the paper industry. Sodium hydroxide is also used in the manufacture of sodium salts and detergents, pH regulation, and organic synthesis. It is used in the Bayer process of aluminium production.[15] In bulk, it is most often handled as an aqueous solution,[29] since solutions are cheaper and easier to handle. Sodium hydroxide is used in many scenarios where it is desirable to increase the alkalinity of a mixture, or to neutralize acids. For example, in the petroleum industry, sodium hydroxide is used as an additive in drilling mud to increase alkalinity in bentonite mud systems, to increase the mud viscosity, and to neutralize any acid gas (such as hydrogen sulfide and carbon dioxide) which may be encountered in the geological formation as drilling progresses. Another use is in Salt spray testing where pH needs to be regulated. Sodium hydroxide is used ...

Thermal decomposition of selected barium compouds in search for an alternativ route for manufacture of sodium hydroxideThermal decomposition of selected barium compouds in search for an alternativ route for manufacture of sodium hydroxide
Previously, sodium hydroxide has been prepared using two processes namely, an Electrolytic process and Caustisization of soda ash. Both methods require a lot of energy and products made under these conditions are very expensive. The present study was aimed at investigating whether barium hydroxide rather than slaked lime can be used in the lime-soda process. The barium hydroxide was obtained from carefully selected barium compounds which thermally decomposed within temperature ranges of 600°C-700°C to barium oxide. The barium compounds used were barium sulphite and barium nitrate. The barium hydroxide was reacted with sodium carbonate and formed sodium hydroxide and barium carbonate as slaked lime in the lime-soda process that produces sodium hydroxide and calcium carbonate. The results have confirmed beyond any reasonable doubt that both barium sulphite and barium nitrate readily decompose thermally in the temperature ranges 650°C-700°C. Barium sulphite decomposes to barium oxide and ...

Sodium hydroxide - Simple English Wikipedia, the free encyclopediaSodium hydroxide - Simple English Wikipedia, the free encyclopedia
Sodium hydroxide is an alkali which is also known as caustic soda. Caustic means "burning" and caustic soda takes its name from the way it can burn the skin. It has the chemical formula of NaOH. It is a base, meaning it has a high pH. It is the most common thing used to raise the pH of solutions; for example, to neutralize an acid. As a solid, the alkali is deliquescent and readily absorbs moisture and carbon dioxide from the air. It dissolves easily in water, and makes the water warm when this happens. Sodium hydroxide is used as a solution called lye to make soap. Lye is also used to unclog drains. Its dissolving properties and its ability to easily break surface tension are fundamental for its uses. It works in two ways. First, it combines with grease to make soap. Second, it dissolves hair (which is soluble in any basic solution). ...

Zinc hydroxide - Formula, Uses, Structure and Solubility | Chemistry LearnerZinc hydroxide - Formula, Uses, Structure and Solubility | Chemistry Learner
It is generally prepared by adding moderate amount of sodium hydroxide solution to a zinc salt solution such as zinc chloride or zinc sulfate. These two compounds react under normal conditions to form a white precipitate of Zn (OH)2. Dilute solution of sodium hydroxide should be used in this reaction in order to prevent the inorganic compound from dissolving. Under normal conditions, the zinc salt dissociates to form a zinc ion that associates with two hydroxide ions from sodium hydroxide solution to form zinc hydroxide.. Zn2++ 2OH- → Zn(OH)2. If excess sodium hydroxide is added to the salt solution, the precipitate of Zn (OH)2 that is formed initially will dissolve to form a form a colorless solution of zincate ion as seen below:. Zn (OH)2 + 2OH- → Zn(OH)42-. This property of zinc hydroxide is extensively used to detect the presence of zinc ions in solution. However, it is not a unique method for testing as there many compounds of aluminum and lead that behave in a very similar ...

Acid-Base titration of Sulphuric acid and Sodium Hydroxide - GCSE Science - Marked by Teachers.comAcid-Base titration of Sulphuric acid and Sodium Hydroxide - GCSE Science - Marked by Teachers.com
Introduction. ACID - BASE TITRATION AIM The aim is to perform an experiment involving the titration of an acid and base to find the end-point of the titration in order to determine the molarity of the sulphuric acid. GENERAL BACKGROUND According to Bronsted and Lowry (1923) an acid is defined as a proton (H+) donor, and a base as a proton (H+) acceptor. For example, sulphuric acid, a strong acid, is a good proton donor while sodium hydroxide, a strong alkali (soluble base) contains the hydroxide ion (OH-) which is a strong proton acceptor. The alkali which produces this OH- ion will neutralize acids by the reaction: H+(aq) + OH-(aq) --, H2O(l) This reaction is common to all neutralization reactions between acids and alkalis in aqueous solution. It should be noted that in aqueous solutions the H+ ions exist in their hydrated forms H+(aq). The most accurate method of measurement is to run the acid into the alkali from a burette. This is known as neutralization by titration. Titration is a ...

Wright Brothers Boulevard in Cedar Rapids back open - KWWL - Eastern Iowa Breaking News, Weather, ClosingsWright Brothers Boulevard in Cedar Rapids back open - KWWL - Eastern Iowa Breaking News, Weather, Closings
CEDAR RAPIDS (KWWL) -- The Cedar Rapids Fire Department says Wright Brothers Boulevard is back open following a tanker rollover that caused a chemical leak.. A semi-tanker carrying more than 50,000 pounds of sodium hydroxide overturned while exiting I-380 onto Wright Brothers Boulevard Wednesday morning.. Police say the driver of the tanker, 39-year old Joe Short of Illinois, was turning left onto Wright Brothers Boulevard from the northbound I-380 ramp when the chemical inside the tanker shifted causing the trailer and the truck to turn on its side.. Short was taken to Mercy Medical Center with non-life threatening injuries. He was ticketed for Failure to Maintain Control.. A small drip of sodium hydroxide from the truck forced crews to established a 150 foot safe zone around the tanker while they cut a hole in the steel tank to create a relief valve in order to off-load the chemical. The truck was transporting the sodium hydroxide from Muscatine to Red Star Yeast in Cedar Rapids.. Sodium ...

A uniaxial natural fabric of Hildegardia populifolia was treated with 5% sodium hydroxide solution for 1 h, and the resulting changes were analyzed by polarized and scanning electron microscopic techniques. The untreated and treated H. populifolia fabric was reinforced in epoxy and toughened with 10% polycarbonate. The variation of the flexural strength and flexural modulus with different fabric contents and fiber orienrations was studied. The effect of sodium hydroxide and a silane coupling agent on the flexural properties of the composite was also studied. It was observed that the flexural properties increased on alkali treatment and when the coupling agent was used.

A series of in vitro laboratory trials and in vivo sheep digestion trials were used to evaluate aerobically or anaerobically fermented perennial ryegrass straw. The laboratory trials consisted of a silage study, where mini-silos were used in a 9 X 2 factorial design with nine levels of whey (0 to 20%) and two levels of sodium hydroxide (0 and 4%). The laboratory trial also included a study of products derived from a semisolid fermentation of ryegrass straw, which involved the acid hydrolysis, neutralization with ammonia and aerobic fermentation with yeast (Candida utilis). In vivo digestion trials with sheep were used to evaluate 0 and 4% sodium hydroxide (NaOH) treated silages as well as the semisolid fermentation products. Silage pH was higher (P,.01) for silages containing 4% NaOH than for controls. NaOH treated and untreated silages were similar in crude protein, content, however, NaOH treated silages were lower (P,.05) in total soluble nitrogen and soluble nonprotein nitrogen. The ...

potassium hydroxidepotassium hydroxide
I wish there was such a thing as a completely natural soap made only from coconut oil, olive oil, essential oils etc. But this is unfortunately impossible. There is absolutely no way to make a bar soap without using lye.. The basic reaction that is needed to make soap, called saponification, cannot occur without some form of lye reacting with some form of oil. Lye is actually a general term for a very strong alkali. There are two alkalis that can be used to make soap: sodium hydroxide (caustic soda) and potassium hydroxide. Both are considered lye, but the potassium hydroxide is not strong enough to make a solid soap. It is only used for making liquid soaps.. Therefore sodium hydroxide cannot be substituted for potassium hydroxide and vice versa because soap making recipes will have different quantity requirements for these two chemicals depending on the kind of soap being manufactured. In addition, the quantities required for soap saponification differ when using caustic soda and hydrated ...

article{e5e225c1-5da3-43d2-a4fa-77b2ea1a9abb, abstract = {Treatment with alkali, particularly overliming, has been widely used as a method for the detoxification of lignocellulose hydrolysates prior to ethanolic fermentation. However, the mechanisms behind the detoxification effect and the influence of the choice of cation have not been well understood. In this study, a dilute acid hydrolysate of spruce and an inhibitor cocktail consisting of six known inhibitors were used to investigate different alkali detoxification methods. The various treatments included the addition of calcium hydroxide, sodium hydroxide, potassium hydroxide, and ammonia to pH 10.0 and subsequent adjustment of the pH to 5.5 with either sulfuric or hydrochloric acid as well as treatment with the corresponding amounts of calcium, sodium, and potassium as sulfate or chloride salts at pH 5.5. An RP-HPLC method was developed for the separation of 18 different inhibitors in the hydrolysate, including furaldehydes and phenolics. ...
CO poisoning: clinical featuresCO poisoning: clinical features
Issue: Desiccated (or dry) CO2 absorbers such as soda lime and Baralyme can degrade inhaled anesthetics to carbon monoxide, and my produce carboxyhemoglobin concentrations in excess of 30%.. Mechanism: These CO2 absorbers contain strong bases (sodium hydroxide and potassium hydroxide) that can extract labile protons from anesthetic molecules, resulting in the production of CO. (There are new CO2 absorbers that do not contain KOH or NaOH, such as Amsorb. These do not react with inhaled agents to produce CO, but they are fairly expensive).. Incidence: The incidence of CO exposure is 0.46% for the first case of the day (2.9% in non-OR settings) and overall incidence is 0.26%.. Factors that increase the production of CO and carboxyhemoglobin:. 1. Inhaled anesthetic used: des,/=enflurane,iso,,halothane=sevo. 2. Absorbent dryness. 3. Type of absorbent (Baralyme,soda lime). 4. Increased temperature. 5. Low fresh gas flow. 6. Increasing anesthetic concentration. 7. Size of patient compared to amount of ...
Soda-lime glass - WikipediaSoda-lime glass - Wikipedia
Soda-lime glass, also called soda-lime-silica glass, is the most prevalent type of glass, used for windowpanes and glass containers (bottles and jars) for beverages, food, and some commodity items. Glass bakeware is often made of tempered soda-lime glass. Soda-lime glass accounts for about 90% of manufactured glass. Soda-lime glass is relatively inexpensive, chemically stable, reasonably hard, and extremely workable. Because it can be resoftened and remelted numerous times, it is ideal for glass recycling. Soda-lime glass is prepared by melting the raw materials, such as sodium carbonate (soda), lime, dolomite, silicon dioxide (silica), aluminium oxide (alumina), and small quantities of fining agents (e.g., sodium sulfate, sodium chloride) in a glass furnace at temperatures locally up to 1675 °C. The temperature is only limited by the quality of the furnace superstructure material and by the glass composition. Relatively inexpensive minerals such as trona, sand, and feldspar are usually used ...

Caustics are substances that burn or corrode via chemical reactions. Most commonly, "caustics" or "caustic tanks" is referring to the use and storage of sodium hydroxide (more commonly referred to as caustic soda). This substance requires a heating solution to stay viscous at room temperature. Caustic potash (potassium hydroxide) and caustic lime (calcium oxide) are other commonly used caustic substances. Each of these chemicals have a myriad of industrial applications including cleaning, chemical pulping, food production, soap manufacturing, and agriculture. ...
Calcium hydroxide - The Full WikiCalcium hydroxide - The Full Wiki
Calcium hydroxide, traditionally called slaked lime, hydrated lime, slack lime, or pickling lime, is a chemical compound with the chemical formula Ca(OH)2. It is a colourless crystal or white powder, and is obtained when calcium oxide (called lime or quicklime) is mixed, or "slaked" with water. It can also be precipitated by mixing an aqueous solution of calcium chloride and an aqueous solution of sodium hydroxide. The name of the natural, mineral form is portlandite. It is a relatively rare mineral, known from some volcanic, plutonic, and metamorphic rocks. It has also been known to arise in burning coal dumps.. When heated to 512 °C, the partial pressure of water in equilibrium with calcium hydroxide reaches 101 kPa and decomposes into calcium oxide and water.[1]. A suspension of fine calcium hydroxide particles in water is called milk of lime. The solution is called lime water and is a medium strength base that reacts violently with acids and attacks many metals in presence of water. It ...

Corneal disease is the second most common cause of blindness in the word. It is estimated that 45 million people worldwide are bilaterally blind and 10 million are affected by corneal blindness. Corneal blindness mostly affects the population in the equatorial zone, due to the high exposure to UV light. Corneal grafting presents complications such as rejections and the lack of donor material and resources. Conventional cornea grafting (keratoplasty) is not advised for patients with bilateral corneal blindness or for those who suffer from a range of clinical problems including tear deficiency, chemical burns and uncontrollable intraocular pressure. At present, an artificial cornea, i.e. a keratoprosthesis (KRPO), is the only alternative to keratoplasty (corneal donor transplantation). Cornea implants consist of a clear optic part and a surrounding ring known as the skirt, which needs to integrate with the sclera of the eye. Currently used skirt materials lead to poor tissue integration, a major ...
Caustic stripping. - TopicCaustic stripping. - Topic
Essentially stripping involves heating up the oil to 50 degrees C and adding a strong solution of Sodium hydroxide ( NaOH, drain cleaner) and water to the oil and mixing it thoroughly. The NaOH, water and FFAs combine to produce soap (saponification)and water. Glycerol is then added and mixed with the oil and as the glycerol settles to the bottom of the vessel it takes most of the soap and water with it. The improvement to the oil is quite spectacular, on my first try I achieved a reduction in titration of 19ml (KOH) to 4.5ml (KOH ...
Potassium HydroxidePotassium Hydroxide
A question which I was once asked was, "Does chlorine react with acid?" And when I gave a quick answer to this question, I assumed that when the person asking it said "Chlorine", he meant Cl2 gas. What I had forgotten was, that some people, including the person who was asking this question, take the word "Chlorine" to be a synonym for Chlorine Bleach. And of course, chlorine bleach reacts with acid! But to understand how such communication errors take place, one must actually understand, What is chlorine bleach?. Most preparations of chlorine bleach, are based on either sodium hypochlorite (NaOCl), or potassium hypochlorite (KOCl), with a generous amount of the corresponding hydroxide added to it, to stabilize it. This modern mixture is prepared industrially, by allowing chlorine gas to react with sodium hydroxide solution, for the sake of argument, which generates a mixture of sodium chloride - i.e., salt - and sodium hypochlorite:. Cl2(g) + 2NaOH(aq) -, NaCl + NaOCl + H2O. What happens ...

Chemicals and Solutions: 95% ethanol. Distilled water. Sodium chloride (1M). Sodium hydroxide (1M). Hydrochloric acid (1M). Acetic acid (1M). Ammonium hydroxide (1M). Materials: Multiple conductivity apparatus. 7 - 250 ml beakers. Procedure: Label 7 beakers to contain the above listed solution. 3/4 fill each beaker with the appropriate solution. Remove the top of the conductivity apparatus carefully and place each solution in its designated place. Replace top carefully.. Push the button on top to check the conductivity of each solution. Discussion: When NaCl, HCl, and NaOH react with water they are completely converted to ions. Therefore their solutions have high electrical conductivity and the light bulb is lit up very brightly. Ammonium Hydroxide and Acetic acid react incompletely with water; they are not completely ionized. Therefore their solutions have only a small electrical conductivity and the light bulb glows dimly. Ethanol and water have covalent bonds and do not conduct ...

Three geosorbents were characterized using 13C-NMR to determine the relative degree of hard and soft carbon. Michigan peat is a relatively young soil from which phenanthrene readily desorbs; Chelsea soil is a high-organic, muck-type top soil with an intermediate hysteresis index; and Lachine shale is a geologically old soil with a high hysteresis index. The sorption isotherms were fit to the Freundlich equation. Soils were aged under anoxic conditions for 2 or 4 months, and the mass of nonradiolabeled phenanthrene was varied to achieve a constant equilibrium aqueous concentration. Radiolabeled phenanthrene in methanol was added to each bottle as a tracer. The bioflasks consisted of a 250-mL flask with a center well for sodium hydroxide (NaOH) and a side arm. A concentrated mineral-nutrient solution and a cell solution of Pseudomonas CRE7, a phenanthrene degrader, were added to the flasks. The NaOH was removed from the center well at sampling to measure the extent of mineralization. Oxygen was ...
1-NAPHTHYLAMINE (1-AMINONAPHTHALENE)1-NAPHTHYLAMINE (1-AMINONAPHTHALENE)
Low molecular amine names are formed by adding -amine as a suffix to the name of the parent compound. In substitutive nomenclature, the prefix amino- is placed before the name of the parent compound to denote the functional group in high molecular amines. Synthetic amines are made mostly by reaction of alcohols with ammonia, catalyzed by metals( nickel or copper) or metal oxide at high temperature. Many methods have been devised for the synthesis of the amines; reacting ammonia with an alkyl halide and neutralizing the resulting alkyl ammonium salt with an alkali, e.g., sodium hydroxide. This procedure yields a mixture of primary, secondary, and tertiary amines that is easily separated into its three components by fractional distillation; boiling methyl isocyanate with caustic potash, heating the alkyl iodides with ammonia; reduction of nitriles with alcohol and sodium; heating the esters of nitric acid with alcoholic ammonia; reducing on nitro-paraffms; action of zinc and hydrochloric acid ...
Sodium - wikidocSodium - wikidoc
Extreme care is required in handling elemental/metallic sodium. Sodium is potentially explosive in water (depending on quantity) and is a caustic poison, since it is rapidly converted to sodium hydroxide on contact with moisture. The powdered form may combust spontaneously in air or oxygen. Sodium must be stored either in an inert (oxygen and moisture free) atmosphere (such as nitrogen or argon), or under a liquid hydrocarbon such as mineral oil or kerosene. The reaction of sodium and water is a familiar one in chemistry labs, and is reasonably safe if amounts of sodium smaller than a pencil eraser are used and the reaction is done behind a plastic shield by people wearing eye protection. However, the sodium-water reaction does not scale up well, and is treacherous when larger amounts of sodium are used. Larger pieces of sodium melt under the heat of the reaction, and the molten ball of metal is buoyed up by hydrogen and may appear to be stably reacting with water, until splashing covers more of ...
Base in Chemistry - Windows to the UniverseBase in Chemistry - Windows to the Universe
Like an acid, a base is a substance capable of dissolving things. Here is a scientific explanation of what a base is: A base is a substance which accepts a proton from another species in a reaction. (Here, "accept" is a passive term for what really happens. A base attacks and "rips" a proton from a substance which has any capability of giving it away. Thus a base accepts a proton the way a thief "accepts" your purse). Bases are classified as either strong or weak depending upon their relative ability to do this. When it does this, it changes the substance it attacks into a different substance. There are many bases. Here are a few: Ammonia (used as a cleaner), Calcium hydroxide (used in mortar for construction), Magnesium hydroxide (otherwise known as milk of magnesia; used as a laxative or antacid), Sodium hydroxide (used as an oven cleaner ...
Fascination About water clean upFascination About water clean up
Pure water features a pH close to 7 (neither alkaline nor acidic). Sea water can have pH values that vary from seven.five to eight.four (reasonably alkaline). New water might have widely ranging pH values according to the geology of your drainage basin or aquifer plus the affect of contaminant inputs (acid rain). When the water is acidic (decreased than 7), lime, soda ash, or sodium hydroxide could be added to boost the pH through water purification procedures. Lime addition increases the calcium ion concentration, Consequently increasing the water hardness. For really acidic waters, pressured draft degasifiers can be an effective way to boost the pH, by stripping dissolved carbon dioxide from the water.[four] Creating the water alkaline can help coagulation and flocculation procedures do the job effectively and in addition helps to reduce the potential risk of direct remaining dissolved from lead pipes and from lead solder in pipe fittings ...

What are the Impurities Present in Wool? How They can be Removed? - Textile LearnerWhat are the Impurities Present in Wool? How They can be Removed? - Textile Learner
iii) Scouring: Scouring of wool differs from cotton. Firstly, wool contains a high percentage (30-60%) of wool grease compared with 0.5% of oil and wax in cotton. Secondly, wool is degraded rapidly with alkali, hence it saponification of oils, and fats is to be done with alkali; it should be done very carefully and below the boiling temperature. Sodium hydroxide is replaced by sodium carbonate, ammonia or ammonium carbonate. Raw wool is scoured by the counter current method, using a machine with four or five bowls arranged in a sequence, so that the wool passes directly out of the first into second and so on. Each bowl has a wringer at the exit, a false bottom and rakes. Below the false bottom is a spirally fluted shaft which rotates and carries the deposited solid dirt to the central outlet for discharge. The rakes make the wool travel forward, beneath the surface of liquor and also agitate to keep the dirt and emulsified grease in suspension. The scouring liquor falls back in the bowl after ...
Pre-treatment effects on coral skeletal delta C-13 and delta O-18 | Earth & Environmental SciencePre-treatment effects on coral skeletal delta C-13 and delta O-18 | Earth & Environmental Science
Pre-treatments are often used to remove organic contaminant material prior to isotopic analyses of coral skeletal samples. Here we conducted three experiments to test the pre-treatment effect of water, 30% hydrogen peroxide (H2O2), and household bleach [5.25% sodium hypochlorite (NaClO3) and 0.15% sodium hydroxide (NaOH)], on the stable isotopic composition of coral skeletal samples. First, using a mass balance approach we calculated the expected change in skeletal delta C-13 due to the removal of all organic carbon. The model showed that (1) the removal of organic carbon (which has a low delta C-13 value relative to skeletal delta C-13) from the skeletal sample should theoretically result in a higher delta C-13 value of the remaining organic-carbon-free carbonate, and that (2) only at the highest concentrations of skeletal organic carbon within the tissue layer of corals is the contribution of the organic carbon to the overall delta C-13 skeletal value potentially large enough to be ...

The most important colorimetric tests that a Newbie will use are the nitrogen tests: ammonia, nitrite and nitrate. Lets tackle ammonia first since it is the most important test, next to salinity, that one runs on a new tank. The test is simple. In an alkaline solution ammonia releases iodine from potassium iodide and produces a yellow to orange color. This is the Nessler test for ammonia. Low concentrations are light yellow and, as they increase, the intensity of the yellow increases until it becomes an orange color. Usually sodium hydroxide is used to get the very high pH needed for the test. This creates a problem as that both calcium and magnesium present in the salt water precipitate and make the sample cloudy. To prevent this, a chemical, often Rochelle salt (potassium sodium tartrate) is added to the sample. This ties up the calcium and magnesium and keeps them in solution. Because there is more calcium and magnesium in a reef versus a fresh water tank, a fresh water kit will not work on ...

Centrifugal forces (the forces that move things away from the center of rotation) send solid particles in the gas outward against the walls of the container. They collect there briefly, then fall to the bottom of the container. Gases from which the particles have been removed then escape from the top of the container. Gaseous emissions. Many different methods are available for removing unwanted gases, most of which are acidic. Scrubbers are smokestack devices that contain a moist chemical such as lime, magnesium oxide, or sodium hydroxide. When gases escape from a factory and pass through a scrubber, they react with the moist chemical and are neutralized. From time to time, the scrubbers are removed from the smokestack, cleaned, and replaced. Another method for controlling gaseous emissions is by adsorption. Activated charcoal is charcoal that has been ground into a very fine powder. In this form, charcoal has the ability to adsorb, or adhere to, other chemicals. When unwanted gases flow over ...
Sources of manganese in the residue from a water treatment plantSources of manganese in the residue from a water treatment plant
Introduction. One of the principal objectives of potable water treatment is purification by removal of suspended solids and dissolved matter (e.g. clay, fine particulate matter, organic and inorganic components, algae, bacteria and viruses) from the raw water. At a conventional water treatment plant (WTP), the suspended solids are removed in clarifiers and sand filters, after prior coagulation with long-chain polymers, addition of flocculation agents such as bentonite and polyacrylamide, and pH correction utilising lime, sodium hydroxide or soda ash. Filter wash-water contains suspended matter removed by the filters. In South Africa, this waste by-product from the clarifiers and wash-water (here termed water treatment residue (WTR) to distinguish it from wastewater sludge) has historically either been disposed of by release into the nearest watercourse, into evaporation ponds or, after partial dewatering, to landfill. Due to high evaporation rates and the perceived availability of land in South ...

Improvement of Nitrification in Rotating Biological Contactors by Means of Alkaline Chemical Addition,Improvement of Nitrification in Rotating Biological Contactors by Means of Alkaline Chemical Addition,
This research examined the short and long-term effect of pH upon the nitrification of wastewater within RBC fixed film systems. In the long-term, the rate of nitrification within an RBC fixed film system was dependent upon pH. The rate of nitrification increased with increasing pH up to a maximum at pH 8.5. Approximately five weeks of operation were required to clearly observe these differences. The response of a nitrifying RBC system to short-term changes in pH was relatively constant from pH 7.0 to pH 8.5. Below pH 7.0, the adverse effect of pH becomes more pronounced. However, the absolute level of nitrification was dictated by the biofilms previous history of nitrification performance. There was no significant difference in the performance of the 2-stage nitrifying RBC systems which received calcium hydroxide, solium carbonate and sodium hydroxide. Higher levels of nitrification for the RBC systems were associated with greater disc biofilm uniformity. In all cases, except for the pH 8.8 RBC of the
