Comparative Study of Anion Exchange Resins Indion H-IP and Indion-NSSR by Application of 131I and 82 Br as a Tracer IsotopeDOI: 10.5923/j.scit.20120205.05 Keywords: Indion H-IP, Indion-NSSR, Solvation Effect, Ion-isotopic Exchange Reactions, Tracer Applications, Reaction Kinetics, Radioactive Isotopes, 131I, 82Br Abstract: The present investigation deals with characterization of weakly basic and strongly basic industrial grade anion exchange resins Indion H-IP and Indion-NSSR. The characterization was performed on the basis of iodide and bromide ion-isotopic exchange reaction kinetics by application of 131I and 82 Br tracer isotopes. It was observed that due to solvation effect the iodide ions are exchanged at faster rate as compared to bromide ions when the experimental conditions are kept identical. For both the ion-isotopic exchange reactions it was observed that the reaction rate is having negative correlationship with temperature and positive correlationship with concentration of exchangeable ions in solution. Also under identical experimental conditions, Indion-NSSR shows higher percentage of ion exchange than Indion H-IP resins.
