The drug-resin complex then coated is shelf stable.

Sodium polystyrene sulfonate is a non-absorbed, cation exchange polymer that contains a sodium counterion.. Sodium polystyrene sulfonate increases fecal potassium excretion through binding of potassium in the lumen of the gastrointestinal tract. Binding of potassium reduces the concentration of free potassium in the gastrointestinal lumen, resulting in a reduction of serum potassium levels. The practical exchange ratio is 1 mEq K per 1 gram of resin.. As the resin passes along the intestine or is retained in the colon after administration by enema, the sodium ions are partially released and are replaced by potassium ions. This action occurs primarily in the large intestine, which excretes potassium ions to a greater degree than does the small intestine. The efficiency of this process is limited and unpredictably variable.. ...

Norfloxacin is a common fluoroquinolones antibacterial drug having the bitter taste which hindered its oral administration. Drug resin complex mask the bitter taste of the drug and hence an attempt has been made in the present study to prepare bitterless Norfloxacin suspension using Ion exchange resins. Norfloxacin was treated with the weak cation exchange resins which form the drug resin complex called resinate. The loading process was optimized for the pH of loading solution and the drug resin ratio. The resinates were evaluated for bulk density, angle of repose, taste masking, and in vitro drug release. Taste evaluation of the drug resinates showed complete masking of the bitterness of the drug. In vitro drug release studies revealed that more than 90% of the drug was released within 20 min from the drug resinates. Sweet palatable aqueous suspension of norfloxacin was formulated successfully with drug-resin complex and it was found to be stable.

Natural tannins have a high affinity to absorb metal ions, proteins and some other biomolecules. In this study, tannins extracted from Terminalia arjuna (Kumbuk) were used to synthesise renewable tannin-phenol-formaldehyde resin systems and a porous modified resin system. A series of resin systems was synthesised by varying the incorporated phenol content. The ion exchange capacities of the resins produced were studied and the resin with the highest ion exchange capacity was selected. It was sulfonated to increase the properties further. A monovalent cation, Na+ was used to estimate the adsorption properties of both sulfonated and unsulfonated resin systems. Solubility and swelling properties of the resins were measured to check their applicability as an ion exchanger in aqueous media at different pH values. Fourier transform infrared spectroscopy (FTIR) analysis was carried out to characterise the synthesised resins. Scanning electronic microscopic (SEM) images were obtained to study the ...

In the present work, a new purification method of anthocyanins with o-dihydroxy arrangement is proposed. This method is based on a ligand-exchange mechanism, using a cationic exchange resin loaded with metallic ions in order to increase the affinity of the resin to the anthocyanin(s) with o-dihydroxy arrangement. This method was used to purify the main anthocyanin (cyanidin-3-glucoside; Cy-3-glc) from the anthocyanic methanolic extract of blue corn. The best sorption result was using Fe(III) in its ion form. The purification procedure begins with the formation of a metal-anthocyanin complex (Cy-3-glc-Fe) which was optimal at pH 5, followed by a NaOH 0.1?M elution process in order to eliminate anthocyanins without o-dihydroxy arrangement, sugars, and organic acids. Finally, the pure anthocyanin is obtained by adding HCl 0.1?M which breaks the metal-anthocyanin complex. ...

Polystyrene sulfonates are polymers derived from polystyrene by the addition of sulfonate functional groups. They are widely used as ion-exchange resins to remove ions such as potassium, calcium, and sodium from solutions in technical or medical applications. Linear ionic polymers are generally water-soluble, whereas cross-linked materials (called resins) do not dissolve in water. These polymers are classified as polysalts and ionomers. Polystyrene sulfonate is usually supplied in either the sodium or calcium form. It is used as a potassium binder in acute and chronic kidney disease for people with hyperkalemia (abnormal high blood serum potassium levels). However, it is unclear if it is medically beneficial and there is concern about possible side effects when it is combined with sorbitol. Polystyrene sulfonates are given by mouth with a meal or rectally by retention enema. Under the name tolevamer, a polystyrene sulfonate was investigated by Genzyme as a toxin binding agent for the treatment ...

The relative activities of four disiloxanes toward the cation exchange resin, which was used as an equilibration catalyst, were determined in such a way that the equilibrium initialy present in an arbitrary chosen equilibrate was disturbed by adding the respective disiloxanes to it, and then by recording the viscosity of the equilibrating mixtures as a function of reaction time.As a result, a set of different viscosity-reaction time relationships was obtained, which implies different activities of disiloxanes toward the catalyst. In this way the following decreasing order of activities was established : 1,3-tetramethyldisiloxane,1,3-divinyltetramethyldisiloxane ,hexamethyldisiloxane ,1,3-bis( 3-carboxypropyl)tetramethyldisiloxane ...

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 ( ...

A comparative study on the adsorption of zinc(II) and cobalt(II) from aqueous solutions onto Indion BSR, an indigenous cation-exchange resin, was undertaken in the present work. Various parameters for the removal of Co(II) and Zn(II) such as the initial solution pH, contact time, resin and metal ion concentration were optimized. The equilibrium data obtained were well fitted by both the Langmuir adsorption isotherm at pH 6.0 for 500 mg resin and the Freundlich adsorption isotherm under optimum conditions of contact time and pH 5.0 for 250 mg resin at 30degreesC. The adsorption of Zn(II) and Co(II) on this cation-exchange resin followed first-order reaction kinetics. Film diffusion of Co(II) and Zn(II) in this ion-exchange resin was shown to be the main rate-limiting step over the concentration range studied. The studies showed that the resin could be used as an efficient adsorbent for the removal of Co(II) and Zn(II) from aqueous solutions. ...

The reaction of glycerol with tert-butyl alcohol in the liquid phase on acid Amberlyst-type ion-exchange resins was studied. The influence of temperature, mole ratio n(TBA)/n(G), water and swelling of gel, and macroreticular type of polymer catalysts on etherification reaction was investigated. The most favourable reaction temperature is 75°C. The conversion of glycerol and yield of glycerol tert-butyl ethers has increased with the mole ratio n(TBA)/n(G). Dry form of macroreticular catalysts provided the best results. Etherification reaction of glycerol with isobutylene in non-aqueous conditions gives the highest yield of desired ethers. The influence of water was studied. The gel forms of ion-exchange resins have very low catalytic activity. It can be concluded that water has an inhibition effect on ion-exchange resins. By comparing the gel and macroreticular forms of Amberlyst ion-exchange resins it can be concluded that very acid forms of macroreticular ion-exchange resins with a high degree ...

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 ...

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.. ...

The growing interest of chemical and oil refining industries in the catalytic oligomerization of alkenes for the production of synthetic fuels and additives formulated around light gasoline olefins is due to recent environmental restrictions and increasing diesel demand. Furthermore, the drive towards sustainability and the emergent contribution of biorefineries for the manufacture of intermediate and platform chemicals envisages olefins produced from biomass derived alcohols as an important feedstock for subsequent oligomerization. Over the last years much work has been published on the catalytic oligomerization of propene, butene, isobutene and isoamylene over cation exchange resins, such as Amberlyst and Purolite, and others like Nafion. For instance, isobutene dimers and trimers are accepted additives for gasoline (octane booster) and diesel (cetane booster) while isobutene higher oligomers can be a source for heavier fuels and synthetic lube oils. This paper presents a deep and critical ...

A second-generation flame spectrometer for the direct determination of phosphorus in water was evaluated. Response to phosphorus in the form of phosphoric acid was linear from 0.5 to 16 ppm phosphorus. The relative standard deviation was approximately constant at 20 percent over the range. River water and municipal sewage effluent were analyzed after the addition of phosphoric acid (1.8 ppm P) and filtration through a series of microporous membranes. Recovery of the added phosphorus averaged 70 percent for the river water and 95 percent for the sewage effluent after treatment with cation exchange resin. There was no clear relation to filter pore size in the range 5 to 0.2 micrometers. Analyses of the higher range EPA Nutrient Reference Samples (approximately 0.5 ppm P) agreed within one standard deviation with the reference values, both for inorganic and total phosphorus. The lower concentration range samples (approximate 0.1 ppm P) gave barely detectable signals ...

What did the Scientists Discover?. Future electronic and optical materials based on colloidal semiconductor nanocrystals will depend upon the stability of these materials under large thermodynamic driving forces for their dissolution, coalescence, or intermixing. Using synchrotron X-ray diffraction (XRD), the Richard Robinson group (Cornell University) directly probed the structure and reaction kinetics of lead sulfide (PbS) nanocrystals (NCs) undergoing cationic exchange to cadmium sulfide (CdS). This system was an ideal candidate for using XRD to study phase transformation kinetics, as the PbS NC precursors have a simple structure and a well-established synthetic chemistry. Also, the cationic exchange kinetics are slow enough to allow for direct interrogation by XRD. For this experiment, the group characterized the mechanism of the transformation, and they measured how quickly ions could diffuse through a shell only 1-2 nm thick around the nanoparticle core.. Via synchrotron XRD ...

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 ...

Two different methods are available for synthesizing random peptide libraries. The first technique is known as Split and Mix method which consists of three basic steps: splitting, coupling and mixing. Firstly, resin beads are split in a number of aliquots that equals the number of building blocks to be utilized in the synthesis (splitting). Then, to each resin aliquot one building block is coupled and the reactions are driven to completion (coupling). Following this step, beads are randomly and thoroughly mixed (mixing) and then re-splitted in the same number of aliquots, achieving a set of homogeneous and equimolar collections of compounds. Repetitive execution of these basic steps for n times will thus produce a rapid increase of newly generated molecules, while bead number remains constant. Resin beads encounter one reactant at a time, no more than one compound per bead can be generated (one-bead one-compound-OBOC-library). As reactions are driven to completion, all peptides are generated ...

A process for the purification of gabapentin by treatment of a crude aqueous gabapentin hydrochloride solution with a strong cationic ion exchange resin.

The prelytic adhesion of immune cytolytic thymus-derived lymphocytes to specific antigen-bearing ascites tumor target cells has been studied. A new assay was used in which adhesions are permitted to form for 2.5 min; the cells are then dispersed to prevent further adhesion, and the predispersion adhesions are quantitated by subsequent 51Cr release from the tumor cells as a result of cytolytic activity of the adhering lymphocytes. There were the following new findings: (a) magnesium is sufficient to support optimal adhesion formation even when EGTA is added to remove contaminating traces of calcium; (b) calcium supports no adhesion formation when traces of contaminating magnesium are removed by pretreating the medium with a chelating ion exchange resin; (c) calcium synergizes with suboptimal magnesium, increasing the apparent adhesion-supporting potency of magnesium 20-fold in the presence of 50 microM calcium; (d) in the presence of optimal magnesium (2--4 mM), calcium has not effect on the ...

Caesium auride (CsAu) is an ionic compound containing the unusual Au− ion first discovered in 1978 in the laboratory of Joseph Lagowski. It is obtained by heating a stoichiometric mixture of caesium and gold; the two metallic-yellow liquids react to give a clear product. The solution in liquid ammonia is brown, and the solid is yellow (the colour of both metals making up the compound); the ammonium adduct is dark blue. Despite being a compound of two metals, CsAu lacks metallic properties since the free electrons in both metals are used up, as in all ionic compounds. The compound reacts violently with water, yielding caesium hydroxide, metallic gold, and hydrogen gas; in liquid ammonia it can be reacted with a caesium-specific ion exchange resin to produce tetramethylammonium auride.

Highlights: • Water-soluble CdZnSe alloyed QDs synthesized by cation exchange reaction. • The as-prepared CdZnSe QDs have fairly good luminescence properties. • The surface defects of obtained QDs were removed due to the alloyed structure. - Abstract: Water-soluble CdZnSe alloyed nanocrystals have been successfully prepared via green cation exchange reaction in aqueous system. The X-ray diffraction (XRD) patterns indicate that the as-prepared nanocrystals had high crystallinity and small particle size of 4-5 nm. The absorption spectra of CdZnSe show red shift of 100 nm from 375 to 475 nm. Moreover, the band-gap photoluminescent (PL) emission has a red shift of 50 nm from 430 to 480 nm with the increase of the reaction time. On the basis of the PL properties and transmission electron microscopy (TEM) images, one kind of core-shell-like structure model was proposed, which resulted from the different cation exchange reaction rates. This structure could greatly improve the luminescence ...

Water chemistry is one of the most important parameters affecting flotation performance. Various types of ions can dissolve and accumulate in process water depending on ore mineralogy, reagent scheme, grinding medium and chemistry of mine site water. Sulfur-based ions (sulfate, thiosulfate, polythionate) are generally observed in flotation of sulfide ores. High concentrations of these ions may reduce efficiency of the flotation process, causing scale problems. Removal of these ions from process water often requires complex water treatment plants with high capital and operating costs. In this study, partial cleaning of water was investigated as an alternative approach for decreasing high sulphate concentrations of 3000–3800 mg/L down to 1000–1500 mg/L, an acceptable concentration for most sulfide ore flotation plants, by using an ion-exchange resin. For this purpose, detailed adsorption tests were performed using a laboratory-scale column system to determine the most suitable type of resin
