The present paper demonstrates application of isotopic tracer technique in characterization of anion exchange resins Dowex-SBR LC and Indion-454 for which 131I and 82Br radio isotopes were used. The characterization was made based on iodide and bromide ion-isotopic exchange reaction kinetic data obtained for the two resins. It was observed that during iodide ion-isotopic exchange reaction performed at 35.0 °C, 1.000 g of ion exchange resins and 0.002 mol/L labeled iodide ion solution, the values of specific reaction rate (min-1), amount of ion exchanged (mmol), initial rate of ion exchange (mmol/min) and log Kd were 0.379, 0.426, 0.161 and 16.2 respectively for Dowex-SBR LC resin, which was higher than the respective values of 0.156, 0.243, 0.038 and 13.4 as that obtained by using Indion-454 resins. The identical trend was observed for the two resins during bromide ion-isotopic exchange reaction. The results of present investigation also indicate that during the two ion-isotopic exchange reactions, for

The counteranion exchange of quaternary 1,2,3-triazolium salts was examined using a simple method that permitted halide ions to be swap for a variety of anions using an anion exchange resin (A¯ form). The method was applied to 1,2,3-triazolium-based ionic liquids and the iodideto- anion exchange proceeded in excellent to quantitative yields, concomitantly removing halide impurities. Additionally, an anion exchange resin (N3¯ form) was used to obtain the benzyl azide from benzyl halide under mild reaction. Likewise, following a similar protocol, bis(azidomethyl)arenes were also synthesized in excellent yields. The results of a proton NMR spectroscopic study of simple azolium-based ion pairs are discussed, with attention focused on the significance of the charged-assisted ( ...

Anion exchange resins (AERs) were compared with aluminum-based coagulants for reducing disinfection by-product (DBP) precursor concentrations from a source water collected in northeast Ohio, USA. Three AERs (IRA-910, IRA-958, and MIEX) were evaluated to determine which resin would remove the most natural organic matter (NOM) and moieties responsible for DBP formation. All the AERs were found to be highly proficient at NOM removal specifically the moieties that absorb UV254 (i.e., chromophores) over 75 min of contact time; however, MIEX removed NOM at a faster rate than IRA-910 and IRA-958 resins. Enhanced coagulation was effective at removing approximately 35% of the NOM and 40-60% of the chromophores and fluorophores (i.e., excitation-emission matrix pairs A and C). DBP formation was determined as a function of pH for the different NOM removal processes. MIEX treatment resulted in significant reduction in DBP concentrations when compared to chlorinating the raw source water. MIEX generally ...

Improved separations of xylose, mannose, galactose, arabinose, glucose, xylitol, arabitol; sorbitol, galactitol, or mannitol (and other monosaccharides and sugar alcohols) from other sugars and sugar alcohols may be achieved by chromatography over hydroxyl-form anion exchange surfaces prepared from anion exchange resins at relatively low hydroxyl concentrations. When a strong base anion exchange resin, such as a chloride-form strong base anion exchange resin, is conditioned with a low concentration of hydroxyl (for example, an NaOH solution with a concentration between 0.1 and 1000 mM, most preferably between 1 and 10 mM), the conditioned resin separates a number of sugars and sugar alcohols from one another, while still allowing ready desorption from the resin.

A multi-step process was developed for microbial d-lactic acid purification, followed by poly-d-lactic acid (PDLA) synthesis via azeotropic polycondensation process. Several anion exchange resins were screened for their binding capacity using model lactic acid solutions. Amberlite® IRA67 (weak base anion exchange resin) showed the highest lactic acid adsorption, with maximum adsorption capacity, qmax, of 136.11 mg lactic acid / g of resin, and was further selected to purify D-lactic acid from DDGS hydrolysates through a three-step process; (1) treatment with 7% w/v activated carbon, (2) acidification of fermentation broth (Amberlite® IRA120) and (3) adsorption of lactic acid by anion exchange (Amberlite® IRA67). At the end of the purification process, 80.4% (w/w) D-lactic acid was recovered with 91.8% (w/w) purity, indicating the effectiveness of the developed downstream process. Furthermore, a clear yellowish solid polymer with a molecular weight of 3010 Da was obtained, suitable for ...

Prior art available in the literature is about the recovery of extraction solvent from degraded lean solvent stream. However, IIP has developed adsorption process for removal of salt from aqueous NMP. In this process aqueous NMP is first treated with a conditioned anion exchange resin to remove chlorides and any acidity. This is followed by treatment with cation exchange resin to remove added alkalinity. But this process does not work when salt content levels are higher than 5000 ppm. Moreover, additional infrastructure i.e. ion exchange columns are needed for this route. But present invention deals with altogether different problem i.e. recovery of extraction solvent from highly concentrated brine solution. To date no solution of such problem is discussed in the open literature. Also no patent is available. The present invention is a new idea generated in our laboratory ...

Millions of people across the Indian subcontinent are at risk of chronic exposure to arsenic and fluoride in aquifers with excess TDS (|500 mg/L). Hybrid anion exchange resins with nanoparticles of zirconium oxide (HAIX-NanoZr) were created for effective fluoride removal; zirconium oxide selectively bound fluoride, silica, and phosphate. The zeta potential of HAIX-NanoZr was directly correlated to the fluoride removal capacity. Thus, to increase fluoride capacity and achieve partial desalination concurrently, a weak acid cation (WAC) exchange pretreatment was used to lower alkalinity, hardness, pH, and TDS. Consistent partial desalination (~50%) occurred in proportion to influent alkalinity and hardness. With regular acid conditioning of WAC, the fluoride capacity of HAIX-NanoZr increased 10x, 300 bed volumes (BVs) to 3500 BVs. Upon regeneration with 2% NaOH, |95% of capacity was restored; fluoride treatment was identical over three consecutive cycles with water from a fluoride-contaminated well (Nakuru

A broad and simple method permitted halide ions in quaternary heteroaromatic and ammonium salts to be exchanged for a variety of anions using an anion exchange resin (A− form) in non-aqueous media. The anion loading of the AER (OH− form) was examined using two different anion sources, acids or ammonium salts, and changing the polarity of the solvents. The AER (A− form) method in organic solvents was then applied to several quaternary heteroaromatic salts and ILs, and the anion exchange proceeded in excellent to quantitative yields, concomitantly removing halide impurities. Relying on the hydrophobicity of the targeted ion pair for the counteranion swap, organic solvents with variable polarity were used, such as CH3OH, CH3CN and the dipolar nonhydroxylic solvent mixture CH3CN:CH2Cl2 (3:7) and the anion exchange was equally successful with both lipophilic cations and anions.

Deionization also called as Demineralization, is an ion exchange resin based process which can generate water, free of dissolved salt. DM process configuration includes basic cationic and anionic beds. Typically, the cation resin operates in the hydrogen cycle. The cations in the water (i.e. calcium, magnesium and sodium) pass through the canion exchange resin where they are chemically exchanged for hydrogen ions. The Water then passes through the anion exchange resin where the anions (i.e. chloride, sulphate, nitrate and bicarbonate) are chemically exchange for hydroxide ions. The final water from this process consists essentially of hydrogen ions and hydroxide ions, which is the chemical composition of pure water.. ...

Colestyramine (INN) or cholestyramine (USAN) (trade names Questran, Questran Light, Cholybar, Olestyr) is a bile acid sequestrant, which binds bile in the gastrointestinal tract to prevent its reabsorption. It is a strong ion exchange resin, which means it can exchange its chloride anions with anionic bile acids in the gastrointestinal tract and bind them strongly in the resin matrix. The functional group of the anion exchange resin is a quaternary ammonium group attached to an inert styrene-divinylbenzene copolymer. Colestyramine removes bile acids from the body by forming insoluble complexes with bile acids in the intestine, which are then excreted in the feces. As a result of this loss of bile acids, more plasma cholesterol is converted to bile acids in the liver to normalise levels. This conversion of cholesterol into bile acids lowers plasma cholesterol levels. Bile acid sequestrants such as colestyramine were first used to treat hypercholesterolemia, but since the introduction of statins, ...

Since colestipol hydrochloride is an anion exchange resin, it may have a strong affinity for anions other than the bile acids. In vitro studies have indicated that colestipol hydrochloride binds a number of drugs. Therefore, COLESTID Tablets may delay or reduce the absorption of concomitant oral medication. The interval between the administration of COLESTID Tablets and any other medication should be as long as possible. Patients should take other drugs at least one hour before or four hours after COLESTID Tablets to avoid impeding their absorption.. Repeated doses of colestipol hydrochloride given prior to a single dose of propranolol in human trials have been reported to decrease propranolol absorption. However, in a follow-up study in normal subjects, single-dose administration of colestipol hydrochloride and propranolol and twice-a-day administration for 5 days of both agents did not affect the extent of propranolol absorption, but had a small yet statistically significant effect on its rate ...

Oxidative damage to red blood cells (RBCs) may contribute to pathogenesis of sickle cell anemia. Reducing the deleterious effects of oxidants by exposing RBCs to a number of antioxidants has been shown to have protective effects against lipid and protein peroxidation. We hypothesize that antioxidants may also have beneficial effects on the abnormal membrane permeability of sickle cells. Increased cation permeability of these cells encourages HbS polymerization by causing RBC dehydration and also leads to externalization of the prothrombotic aminophospholipid phosphatidylserine (PS). Three antioxidants with different mechanisms of action were investigated - dithiothreitol, N-acetylcysteine, and quercetin. All three were found to inhibit the main cation pathways responsible for dehydration - the deoxygenation-induced cation conductance (or Psickle), the Ca2+-activated K+ channel (or Gardos channel), and the K+-Cl− cotransporter. They also reduced Ca2+-induced PS exposure and hemolysis. Findings provide

Considering the performance of parent Fe(III)-Cu(II) binary oxide nanoparticles in removing numerous contaminants from water, in order to prevent the release of the nanostructures into the cleaned water a deposit with the same composition was introduced into the matrix of a synthetic porous material (ion exchange resin), whereby a hybrid ion exchanger (HIX) was obtained. Amberlite 900 Cl, a commercially available strongly basic macroreticular anion exchanger, was used as the supporting material. The inorganic deposit was introduced into its structure in two steps performed batchwise at ambient temperature. Fe(III)-Cu(II) binary oxide could be deposited into the matrix of the strongly basic anion exchanger owing to the affinity of its functional groups for FeCl4− and CuCl42− ions. When in the ion exchange reaction the anion exchanger bound both the ions and the reaction medium alkalized, the respective oxides FeOOH and CuO precipitated in its structure. The oxide deposit was introduced into ...

Figure 2 Separation of a 1 µL sample injection using UHPLC. A flow rate of 0.8 mL/min, nearly half that of the HPLC separation, was used for elution of the sample using an X-PressPak C18S column with 2 µm particles (2.1 mm i.d. X 50 mm L). This resulted in an analysis time of 1.3 min, approximately 7 times faster than the HPLC separation. The gradient elution program of 1.5 min is 10 times shorter than that for HPLC..

Lead was also used, in later times, to seal tin cans when canning of meat was first introduced: they didnt understand the connection even in the 19th century. Sams long time successor in the Navy Victualling office in the 19th century decided that HM Navy should have the new tinned meat - the ratings were suspicious of the new food preferring the old salt pork (which Sams ratings would have had). They called the new canned meat sweet FA - commenting on the unknown origins of the meat. Sweet FA was Sweet Fanny Adams a London girl who was abducted, abused, murdered and dumped. The case was a newspaper sensation - she was always called Sweet Fanny Adams. The ratings were right to be suspicious: lead poisoning is thought to have been a main cause for the disaster of the vanished Franklin expedition to discover the NW passage. Probably language hat is now going to tell us all that this is *not* the derivation of sweet FA, but it is what I read somewhere (probably to do with the Franklin ...

Here, we developed a straightforward methodology to generate TCRαβ negative (allogeneic) cells for CAR-T cell therapies. With an early and transient expression of an anti-CD3 CAR in the engineered donor T cells, we programmed these cells to self-eliminate the TCR+ cell population and obtained an ultrapure TCRαβ- population (99-99.9%) at the end of the CAR-T production. This novel and easy-to-implement procedure preserves the production yield and cell fitness and has the potential to streamline the manufacturing of

Vadim- I have re-nickelated Ni-NTA-agarose resins with varying success. I believe Qiagen provides a protocol for doing this. If I remember correctly, it involves stripping the resin with EDTA and then passing nickel sulfate over the column. Alternatively, I have also used Ni-NTA columns many more than 5 times and have had pretty good resolution. Since these resins are available for about $5/ml, I would suggest using the resin as long as you still get good resolution and then either replace it (if it is a relatively small volume), or attempting to regenerate it if it is a large volume ...

What does dental bonding involve?. To begin, the dentist will isolate the teeth included in the procedure, etching them in preparation for bonding. After applying the etching conditioning liquid, the surface of the teeth will have small crevices that allow the tooth stronger adhesion with the bonding agent. The dentist will then apply a bonding resin which cements the composite in place. After several layers of tooth-colored composite are applied, the composite and bonding resin are shaped and hardened with a specially calibrated light. Once the composite is fully set, the bonded areas are smoothed, buffed, and polished to blend in naturally with the surrounding teeth. If you want to regain confidence in your smile, contact our practice to learn more about bonding.. ...
