The photoreduction of H(2)O(2) by Synechococcus sp. PCC 7942 and UTEX 625. (1/32)

It has been claimed that the sole H(2)O(2)-scavenging system in the cyanobacterium Synechococcus sp. PCC 7942 is a cytosolic catalase-peroxidase. We have measured in vivo activity of a light-dependent peroxidase in Synechococcus sp. PCC 7942 and UTEX 625. The addition of small amounts of H(2)O(2) (2.5 microM) to illuminated cells caused photochemical quenching (qP) of chlorophyll fluorescence that was relieved as the H(2)O(2) was consumed. The qP was maximal at about 50 microM H(2)O(2) with a Michaelis constant of about 7 microM. The H(2)O(2)-dependent qP strongly indicates that photoreduction can be involved in H(2)O(2) decomposition. Catalase-peroxidase activity was found to be almost completely inhibited by 10 microM NH(2)OH with no inhibition of the H(2)O(2)-dependent qP, which actually increased, presumably due to the light-dependent reaction now being the only route for H(2)O(2)-decomposition. When (18)O-labeled H(2)O(2) was presented to cells in the light there was an evolution of (16)O(2), indicative of H(2)(16)O oxidation by PS 2 and formation of photoreductant. In the dark (18)O(2) was evolved from added H(2)(18)O(2) as expected for decomposition by the catalase-peroxidase. This evolution was completely blocked by NH(2)OH, whereas the light-dependent evolution of (16)O(2) during H(2)(18)O(2) decomposition was unaffected.  (+info)

The effects of ammonia on pancreatic enzyme secretion in vivo and in vitro. (2/32)

BACKGROUND: Recent studies clearly demonstrate that Helicobacter pylori (H. pylori) infection of the stomach causes persistent elevation of ammonia (NH3) in gastric juice leading to hypergastrinemia and enhanced pancreatic enzyme secretion. METHODS: The aim of this study is to evaluate the influence of NH4OH on plasma gastrin level and exocrine pancreatic secretion in vivo in conscious dogs equipped with chronic pancreatic fistulas and on secretory activity of in vitro isolated acini obtained from the rat pancreas by collagenase digestion. The effects of NH4OH on amylase release from pancreatic acini were compared with those produced by simple alkalization of these acini with NaOH. RESULTS: NH4OH given intraduodenally (i.d.) in increasing concentrations (0.5, 1.0, 2.0, 4.0, or 8.0 mM/L) resulted in an increase of pancreatic protein output, reaching respectively 9%, 10%, 19%, 16% and 17% of caerulein maximum in these animals and in a marked increase in plasma gastrin level. NH4OH (8 x 0 mM/L, i.d.) given during intravenous (i.v.) infusion of secretin (50 pmol/kg-h) and cholecystokinin (50 pmol/kg-h) reduced the HCO3 and protein outputs by 35% and 37% respectively, as compared to control obtained with infusion of secretin plus cholecystokinin alone. When pancreatic secretion was stimulated by ordinary feeding the same amount of NH4OH administered i.d. decreased the HCO3- and protein responses by 78% and 47% respectively, and had no significant effect on postprandial plasma gastrin. In isolated pancreatic acini, increasing concentrations of NH4OH (10(-7)-10(-4) M) produced a concentration-dependent stimulation of amylase release, reaching about 43% of caerulein-induced maximum. When various concentrations of NH4OH were added to submaximal concentration of caerulein (10(-12) M) or urecholine (10(-5) M), the enzyme secretion was reduced at a dose 10(-5) M of NH4OH by 38% or 40%, respectively. Simple alkalization with NaOH of the incubation medium up to pH 8.5 markedly stimulated basal amylase secretion from isolated pancreatic acini, whereas the secretory response of these acini to pancreatic secretagogues was significantly diminished by about 30%. LDH release into the incubation medium was not significantly changed in all tests indicating that NH4OH did not produce any apparent damage of pancreatic acini and this was confirmed by histological examination of these acini. CONCLUSIONS: 1. NH4OH affects basal and stimulated pancreatic secretion. 2. The excessive release of gastrin may be responsible for the stimulation of basal pancreatic enzyme secretion in conscious animals, and 3. The inhibitory effects of NH4OH on stimulated secretion might be mediated, at least in part, by its direct action on the isolated pancreatic acini possibly due to the alkalization of these acini.  (+info)

The oxidation state of the photosystem II manganese cluster influences the structure of manganese stabilizing protein. (3/32)

Exposure of photosystem II membranes to trypsin that has been treated to inhibit chymotrypsin activity produces limited hydrolysis of manganese stabilizing protein. Exposure to chymotrypsin under the same conditions yields substantial digestion of the protein. Further probing of the unusual insensitivity of manganese stabilizing protein to trypsin hydrolysis reveals that increasing the temperature from 4 to 25 degrees C will cause some acceleration in the rate of proteolysis. However, addition of low (100 microM) concentrations of NH2OH, that are sufficient to reduce, but not destroy, the photosystem II Mn cluster, causes a change in PS II-bound manganese stabilizing protein that causes it to be rapidly digested by trypsin. Immunoblot analyses with polyclonal antibodies directed against the N-terminus of the protein, or against the entire sequence show that trypsin cleavage produces two distinct peptide fragments estimated to be in the 17-20 kDa range, consistent with proposals that there are 2 mol of the protein/mol photosystem II. The correlation of trypsin sensitivity with Mn redox state(s) in photosystem II suggest that manganese stabilizing protein may interact either directly with Mn, or alternatively, that the polypeptide is bound to another protein of the photosystem II reaction center that is intimately involved in binding and redox activity of Mn.  (+info)

Efficacy of common laboratory disinfectants on the infectivity of Cryptosporidium parvum oocysts in cell culture. (4/32)

Nine liquid disinfectants were tested for their ability to reduce infectivity of Cryptosporidium parvum oocysts in cell culture. A 4-min exposure to 6% hydrogen peroxide and a 13-min exposure to ammonium hydroxide-amended windshield washer fluid reduced infectivity 1,000-fold. Other disinfectants tested (70% ethanol, 37% methanol, 6% sodium hypochlorite, 70% isopropanol, and three commercial disinfectants) did not reduce the infectivity after a 33-min exposure. The results indicate that hydrogen peroxide and windshield washer fluid or ammonium hydroxide disinfectant may be suitable laboratory disinfectants against C. parvum oocysts.  (+info)

Structural determination of lipid A of the lipopolysaccharide from Pseudomonas reactans. A pathogen of cultivated mushrooms. (5/32)

The chemical structure of lipid A from the lipopolysaccharide of the mushroom-associated bacterium Pseudomonas reactans, a pathogen of cultivated mushroom, was elucidated by compositional analysis and spectroscopic methods (MALDI-TOF and two-dimensional NMR). The sugar backbone was composed of the beta-(1'-->6)-linked d-glucosamine disaccharide 1-phosphate. The lipid A fraction showed remarkable heterogeneity with respect to the fatty acid and phosphate composition. The major species are hexacylated and pentacylated lipid A, bearing the (R)-3-hydroxydodecanoic acid [C12:0 (3OH)] in amide linkage and a (R)-3-hydroxydecanoic [C10:0 (3OH)] in ester linkage while the secondary fatty acids are present as C12:0 and/or C12:0 (2-OH). A nonstoichiometric phosphate substitution at position C-4' of the distal 2-deoxy-2-amino-glucose was detected. Interestingly, the pentacyl lipid A is lacking a primary fatty acid, namely the C10:0 (3-OH) at position C-3'. The potential biological meaning of this peculiar lipid A is also discussed.  (+info)

Identification of the extracellular loop 2 as the point of interaction between the N terminus of the chemokine MIP-1alpha and its CCR1 receptor. (6/32)

Macrophage inflammatory peptide-1alpha (MIP-1alpha)/CC-chemokine receptor ligand 3 is an 8-kDa peptide that induces chemotaxis of various lymphocytes to sites of inflammation through interaction with the G protein-coupled chemokine receptors CCR1 and CCR5. We recently described the preparation of a photoactivatable derivative of MIP-1alpha labeled with a benzophenone group at the extreme N-terminal end, which is a determinant for the agonist character of chemokines. Benzophenone-MIP-1alpha is a full agonist that specifically and covalently labels CCR1 and CCR5 receptors upon irradiation. In the present study, we use enzymatic and chemical cleavage methods on wild-type and mutated CCR1 receptors to show that the N terminus of the chemokine MIP-1alpha interacts in a specific manner with the second extracellular loop of the CCR1 receptor, within a segment comprising amino acids 178 to 194. This is the first report on the direct identification of a contact point between the N terminus of a chemokine and its membrane-bound receptor. The work shows that the part of chemokines that is endowed with agonist properties interacts with extracellular parts of the receptor rather than the transmembrane core of the protein.  (+info)

Ammonium hydroxide hydrolysis: a valuable support in the MALDI-TOF mass spectrometry analysis of Lipid A fatty acid distribution. (7/32)

Lipid A is the lipophilic moiety of lipopolysaccharides (LPSs), the major components of the external membrane of almost all gram-negative bacteria. It is responsible for the toxicity of LPS and has a heterogeneous structure composed of a bis-phosphorylated glucosamine disaccharide backbone that is acylated at the positions 2, 3 of the GlcN I (proximal) and GlcN II (distal) residue with O- and N-linked 3-hydroxy fatty acids (primary substitution). These fatty acids are further acylated by means of their 3-hydroxy groups (secondary substitution). The toxicity of Lipid A is dependent on its primary structure; the number, the length, and the distribution of the fatty acids on the disaccharide backbone strongly influence the endotoxic activity. In this paper a general and easy methodology to obtain secondary fatty acid distribution, which is one of the most difficult issues in the structural determination of Lipid A, is proposed. The method combines ammonium hydroxide hydrolysis and matrix assisted laser desorption ionization (MALDI)-mass spectrometry analysis and has been successfully proven with five different Lipid A species. The procedure exploits the lower stability under mild alkaline conditions of acyl and acyloxyacyl esters with respect to that of the acyl and acyloxyacyl amides. The partially degraded Lipid A species obtained are analyzed by MALDI-MS. The generality of this approach was tested on five Lipid As, namely those arising from Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, Pseudomonas reactans, and Burkholderia caryophylli.  (+info)

Decrease in the efficiency of the electron donation to tyrosine Z of photosystem II in an SQDG-deficient mutant of Chlamydomonas. (8/32)

Photosystem (PS) II activity of a sulfoquinovosyl diacylglycerol (SQDG)-deficient mutant (hf-2) of Chlamydomonas was partially decreased compared with that of wild-type. The susceptibility to 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) was also modified in the mutant. Photometric measurements in the isolated thylakoid membranes of hf-2 revealed that the lowered activity in the mutant was derived from a decrease in the efficiency of the electron donation from water to tyrosine Z, not from the efficiency of the electron transport from Q(A) to Q(B). This result was confirmed by the decay kinetics of chlorophyll fluorescence determined in vivo. We conclude that SQDG contributes to maintaining the conformation of PSII complexes, particularly that of D1 polypeptides, which are necessary for maximum activities in Chlamydomonas.  (+info)

This inaccurate notion has been spread by some movies and TV personalities. Ammonia is naturally occurring, found in the human body, beef, other proteins, and virtually all foods. It plays an important role in the bodys nitrogen cycle and in helping the body synthesize the protein. It also maintains the pH level that the body needs.. One form of ammonia - ammonium hydroxide - is used in processing foods like baked goods, cheeses, chocolates and some beef products. This is not the same type of ammonia in household cleaners. It is classified as safe by the U.S. Food and Drug Administration (FDA) and is approved in most other countries, including the European Union. When used for meat processing, ammonium hydroxide creates an environment that is unfriendly to pathogenic bacteria, such as E. coli O157:H7 and provides a significant food safety benefit. ...
Alzheimers disease is the leading cause of dementia in the elderly. Pathologically it is characterized by the presence of amyloid plaques and neuronal loss within the brain tissue of affected individuals. It is now widely hypothesised that fibrillar structures represent an inert structure. Biophysical and toxicity assays attempting to characterize the formation of both the fibrillar and the intermediate oligomeric structures of Aβ typically involves preparing samples which are largely monomeric; the most common method by which this is achieved is to use the fluorinated organic solvent 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). Recent evidence has suggested that this method is not 100% effective in producing an aggregate free solution.

Ammonium lactate is a combination of lactic acid and ammonium hydroxide. Ammonium lactate is a moisturizer. Ammonium lactate is used to treat dry, scaly, itchy skin. Ammonium lactate may also be used for purposes not listed in this medication guide.
Actual and postulated roles of glycerophospholipids in a number of biological systems, processes, and disease states have been increasingly realized. Recently, choline glycerophospholipids, multispecies 1-(fatty)alkyl-2-acetoyl-glycerophosphatidylcholine (AEPC, AEGPC), have been shown to have structures in common with Antihypertensive Polar Renomedullary Lipid (APRL), and also of native Platelet Activating Factor (PAF, 1, representative molecular species).^ The chemical syntheis of three bioisosteric analogs (2-4) of PAF/APRL (1) was undertaken: 3- 3-(hexadecyloxy)-2-acetoxy)propoxy hydroxyphosphonyl propyl trimethylammonium hydroxide (2); 3- 2-(ethoxy)-3-(hexadecyloxy)-propoxyl hydroxy- phosphonyl propyl trimethylammonium hydroxide (4); and trimethyl (3-phosphonopropyl)ammonium hydroxide, mono-2-acetamido-3-(hexadecyloxy)propyl ester (5). The rationale and design, routes of chemical synthesis, purification, and structure confirmation of these analogs is discussed. The synthesis of a key

Jacqueline, I dont do as much GMA as I used to so these suggestions may not be the most helpful. I always found that a few drops, number depending upon the size of your water bath, of ammonium hydroxide always helped flatten and expand the sections. I did this using a room temperature water bath. Also I found GMA sections harder to keep flat and properly expanded the thicker they were cut. We routinely cut GMA at 1-2 microns rather then 5.

Although inflammation and protease/antiprotease imbalance have been postulated to be critical in cigarette smokeCinduced (CS-induced) emphysema, oxidative stress has been suspected to play an important role in chronic obstructive pulmonary diseases. transcription factor which, upon activation in response to oxidative or electrophilic stress, detaches from its cytosolic inhibitor, Keap1, translocates to the nucleus, and binds to the antioxidant response element (ARE) in the promoter of target genes, leading to their transcriptional induction (13). Though little is known about Nrf2-regulated genes in the lungs, the recognized members of this group include several critical antioxidant genes, such as heme oxygenase-1 (HO-1), Cglutamyl cysteine synthase (-GCS), and several members of the glutathione S-transferase (GST) family (13).

Mixing about 1 part HCl (Which can be found at most hardware stores, also known as Muriatic Acid. Ask for concrete cleaner.) into 2 parts Hydrogen peroxide (normally used for cleaning cuts) you can make a fairly powerful etchant. Use gloves and dont breathe the fumes though. This will etch a 3"x5" board in less than 10 minutes. No need to heat it up. I usually like to drill a small hole through the board on a corner and thread a wire or nylon string through to help agitate / remove the board. When the board is done etching, the etchant will probably look like green kool-aid, from the copper content in it. This stuff is highly corrosive and will burn skin, which is why you should wear gloves. But it is easy to handle, and fairly easy to dispose of. the etchant is easily deactivated with baking soda. Pour enough baking soda into it slowly (to keep it from boiling and overflowing... remember what happens with baking soda/vinegar? ya...) until it is a solid mass, then leave it in the sun to dry. ...

Youve actually come upon a fundamental limitation of computing in general, and binary real number data representation in particular. Floating point numbers are represented as the sum of positive and negative powers of 2, e.g. 2.125 = 2 + 1/8 = 2^1 + 2^-3 = binary 10.001. However, just like numbers such as 1/7 cant be represented exactly in finite-precision decimal, there are plenty of real numbers within the range of representable values that cant be represented exactly in finite-precision (aka digital) binary. So theres always a danger when comparing floating point numbers that the conversion from a decimal number in your code to the binary number in the CPU will have a rounding error that makes it different than the number to which you are comparing it. For a minimal example of this, try this code: ...

In recent years, galvanic replacement reactions have been successfully employed to produce hollow bimetallic nanostructures of a range of shapes, yet to date there has been no example of the formation of hollow triangular AuAg nanostructures from a Ag nanoprism template. In this manuscript the first example of the synthesis of enclosed triangular AuAg nanostructures (triangular nanoboxes) via galvanic replacement reactions from Ag nanoprisms is reported. These triangular nanoboxes are studied by TEM and HAADF-STEM imaging to elucidate their structure. These studies show that the nanostructures are hollow and do not consist of a Ag core surrounded by a Au shell. Discrete dipole approximation calculations for the extinction spectra are carried out and provide additional evidence that the nanostructures are hollow. These new triangular nanoboxes are very attractive candidates for encapsulation and transport of materials of interest such as drugs, radioisotopes, or magnetic materials. ...
The present invention provides methods of processing biomass containing a cellulosic material that include contacting the cellulosic material with magnesium hydroxide to adjust the pH of the material before and/or after a high temperature and high pressure pretreatment step. The use of magnesium hydroxide provides a safer alternative to using ammonium hydroxide for pH adjustment, a more stable, buffered environment for improved operability in pH control, with similar or improved conversion of biomass to fermentable sugars, and similar or improved reduction of inhibitors during the subsequent hydrolysis or saccharification process.

Novel gas sensors embroidered into fabric substrates based on polymers/ SWNT-COOH nanocomposites were proposed in this paper, aiming for their use as a wearable electronic nose (e-nose). The fabric-based chemical gas sensors were fabricated by two main processes: drop coating and embroidery. Four potential polymers (PVC, cumene-PSMA, PSE and PVP)/functionalized-SWCNT sensing materials were deposited onto interdigitated electrodes previously prepared by embroidering conductive thread on a fabric substrate to make an optimal set of sensors. After preliminary trials of the obtained sensors, it was found that the sensors yielded a electrical resistance in the region of a few kilo-Ohms. The sensors were tested with various volatile compounds such as ammonium hydroxide, ethanol, pyridine, triethylamine, methanol and acetone, which are commonly found in the wastes released from the human body. These sensors were used to detect and discriminate between the body odors of different regions and exist in various

It has been proposed as a candidate bioenergy crop because of its high productivity and its ability to grow on marginal farmlands. The goal of this study was to identify processing options for its enzymatic and fermentative conversion to ethanol. Reed canary grass, which was field grown and harvested at early and late maturities, was extensively analyzed for composition in a previous study. Samples were pretreated either using ...

Background: We and others have reported that myocardial protein phosphatase 1(PP1) activity in the end-stage heart failure (HF) is abnormally increased and contributes to the depressed cardiac function. In this regard, in vivo myocardial PP1 inhibition via endogenous cytosolic inhibitors such as inhibitor-2 (INH-2) has prevented HF progression by augmenting phospholamban (PLN) phosphorylation and thereby increasing cardiac function in the genetic cardiomyopathy model. However, it remained uncertain how INH-2, a cytosolic protein, exerts PP1 inhibition in the sarcoplasmic reticulum (SR). To this end, we investigated the molecular mechanism by which INH-2 inhibits PP1 and regulates contractility in cardiomyocytes.. Methods and Results: Cardiomyocytes were enzymatically isolated from six week-old male Wistar rats (n=10) and subjected to either adenoviral INH-2 infection or chemical PP1 inhibition by an application of 0.01-1microM of tautomycin (TM) and tautomycetin (TMC), followed by assessment of ...
Our study evaluated the effects of low voltage electrical stimulation (ES) during bleeding and hot boning at 1 hr postmortem on loin eye (LE) and top round (TR) muscles. Possibly because of relatively slow initial chilling rate used in our study, hot-boned (HB) muscles, even without ES, were comparable to conventionally chilled and boned counterparts. In fact, coupling ES with HB proved less desirable than HB only ...

Ultra-Etch etchant is a 35% phosphoric acid solution. It features ideal viscosity, which, along with the use of the Blue Micro™ or Inspiral™ Brush tip, facilitates precision placement and superior control. Ultra-Etch etchant is self-limiting in its depth of etch (average depth of 1.9μm with 15-second etch),1 creating an etch pattern that adhesives can penetrate for increased bond strength and reduced sensitivity. Studies demonstrate that Ultra-Etch etchants unique self-limiting chemistry creates an optimal surface to receive resin.2 Though Ultra-Etch etchant is viscous, it can penetrate into the smallest fissures or occlusal surfaces due to physical and chemical properties that promote capillary action. Its ideal viscosity maintains a layer thick enough to prevent premature drying.. ...

I just heard that still small voice deep inside of me that said, Gena your body is dying. And I walked out of the bathroom and he just took one look at me and he knew; Im about to lose my wife," Gena Norris said.. Chuck Norris continued, "Well I saw death in her eyes. I saw her dying and I said you know Ive got to do something.". He went on, "Well its the helpless feeling, you know cause Im kind of a take charge guy, and then here I have something where I cannot do anything and it was, it was horrifying and, and uh, I just thank, thank God that we were able to weather it and that she did get better and I got my wife back.". It was a few years back that this happened, when Gena explained, she ended up in an emergency room for "five or six nights in a row.". "And by the fourth, fifth, sixth night, the burning just kept traveling and I would go in and theyd say, Well whats wrong with you? And Im like I, I dont know. I dont feel good.

The effectiveness of four commercial disinfectants including ammonium hydroxide, phenol, Eco.Bio (combination of QACs and gluteraldehyde) and Virox (combination of peracetic acid and hydrogen peroxide) was evaluated against unsporulated E. tenella oocysts which were obtained from naturally infected birds with ceccal coccidiosis then propagated in broiler chicks reared on wire cage and fed anticoccidial free starter ration from day one of rearing till the end of experiment. The oocysts were exposed to the disinfectants at different concentrations and different contact times. In addition, the effect of some environmental factors including temperature, pH and presence of organic matter on the efficiency of these disinfectants was also studied. Based on obtained results of the current study, it was observed that the most effective disinfectants against unsporulated E. tenella oocysts were ammonium hydroxide 5% and 10%, Phenol 10%, while Eco. Bio and Virox were less effective. Also, the results ...

The disinfectants TriGene, bleach, ethanol and liquid hand soap, and water and temperature were tested for their ability to kill bloodstream forms of Trypanosoma brucei, epimastigotes of Trypanosoma rangeli and promastigotes of Leishmania major. A 5-min exposure to 0.2% TriGene, 0.1% liquid hand soap and 0.05% bleach (0.05% NaOCl) killed all three trypanosomatids. Ethanol and water destroyed the parasites within 5 min at concentrations of 15-17.5% and 80-90%, respectively. All three organisms were also killed when treated for 5 min at 50°C. The results indicate that the disinfectants, water and temperature treatment (i.e. autoclaving) are suitable laboratory hygiene measures against trypanosomatid parasites.
Klüber Lubrication, a worldwide manufacturer of specialty lubricants, has introduced Klüberpaste ME 31-52, is a white/beige lubricating paste based on mineral oil, calcium complex soap and inorganic solid lubricants. Besides its application as a universal assembly paste, the paste offers benefits in friction points with small to minimum motion under high static and dynamic loads.. Klüberpaste ME 31-52 can be used for the assembly of frictional connections, e.g. annular springs or split taper sleeves, and positive connections, e.g. bearing seats, profiled guides, etc. The product is designed for the lubrication of clamping chucks. High precision and constant clamping forces are essential requirements in chucks. Any decrease of the clamping force may cause tools or workpieces to become loose.. Klüberpaste ME 31-52 improves the sliding behavior of moving chuck components, enables a good transmission of clamping forces and can therefore be used in all types of chucks, such as scroll, cam and ...
Pseudomonas tolaasii is a species of Gram-negative soil bacteria that is the causal agent of bacterial blotch on cultivated mushrooms (Agaricus bisporus). It is known to produce a toxin, called tolaasin, which is responsible for the brown blotches associated with the disease. It also demonstrates hemolytic activity, causing lysis of erythrocytes. Based on 16S rRNA analysis, P. tolaasii has been placed in the P. fluorescens group. Brodey (1991).

The West Africa Ebola virus (EBOV) outbreak has highlighted the need for effective disinfectants capable of reducing viral load in a range of sample types, equipment and settings. Although chlorine-based products are widely used, they can also be damaging to equipment or apparatus that needs continuous use such as aircraft use for transportation of infected people. Two aircraft cleaning solutions were assessed alongside two common laboratory disinfectants in a contact kill assay with EBOV on two aircraft relevant materials representative of a porous and non-porous surface. A decimal log reduction of viral titre of 4 is required for a disinfectant to be deemed effective and two of the disinfectants fulfilled this criteria under the conditions tested. One product, Ardrox 6092, was found to perform similarly to sodium hypochlorite, but as it does not have the corrosive properties of sodium hypochlorite, it could be an alternative disinfectant solution to be used for decontamination of EBOV on sensitive
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 ...
