Ion exchange is a reversible process. Thus, once the media becomes exhausted, it can be regenerated and the resin is returned to its original ionic form for reuse. Regeneration involves pollutants desorption from the media using processes that drive the pollutants from the media without destroying it. In previous studies, cation exchange resin was used for mature municipal landfill leachate tre...

The influence of simple salts on the ion exchange and protonation equilibria of an amphoteric ion-exchange resin, which has strong base and weak acid moieties in a single functional group fixed onto the styrene-DVB matrix, has been investigated. Concentrations of ionic species in the amphoteric ion-exchange resin in equilibrium with various sodium salt solutions were estimated by (23)Na NMR spe...

The Jaff#{233} reaction is commonly used to determine the concentration of creatinine in urine and serum by measuring the color produced when picric acid and sodium hydroxide solutions are combined with urine or protein-free filtrate from serum. As is well known, substances other than creatinine react to give positive error, the relative amount of interference usually being much greater in seru...

There are many reports in the literature referring to the utilization of drug bound to ion-exchange resin (drug-resinate), especially in the drug delivery area. Ion-exchange resin complexes, which can be prepared from both acidic and basic drugs, have been widely studied and marketed. Salts of cationic and anionic exchange resins are insoluble complexes in which drug release results from exchan...

Ion exchange resins have versatile properties as drug delivery vehicles and have been extensively studied in the development of novel drug delivery systems1. Cation exchange resins containing strong sulfonic acid group form a strong bond with cationic drugs and elution of drug from resinates is slower2. Formulations based on ion exchange resins are successfully marketed viz Pennkinetic system b...

adsorption of cations al, zn, fe, cr and pb from aqueous solution of hydrogen peroxide using ir-120 cation-exchange resin was studied. the removal percentage of the cations was examined by varying experimental conditions (such as ph of the hydrogen peroxide solution, temperature, contact time and dosage of adsorbent) in a stirred-batch system. under the optimal conditions (ph=1, t=25oc, contact...
