Comparative Study of Indion-870 and Duolite A-611 Anion Exchange Resins by Application of 131I and 82 Br as a Tracer Isotopes

In the present investigation we have characterized strong and weak base anion exchange resins on the basis of their performance under different operational parameters. The radioactive tracer isotopes 131I and 82Br were used to trace the ion-isotopic exchange reactions. In case of iodide and bromide ion-isotopic exchange reactions using both the resins, there exists a strong positive correlationship between amount of ions exchanged and ionic concentration, while strong negative correlationship exist between amount of ions exchanged and temperature of exchanging medium. The values of specific reaction rates (min-1), percentage / amount of ions exchanged, and distribution coefficient calculated for Duolite A-611 were higher than that calculated for Indion-870, indicating superior performance of Duolite A-611 over Indion-870.
