Comparative Study of Indion-820 and Indion -930A Ion Exchange Resins by Application of 131I and 82 Br as a Tracer Isotopes

The present study demonstrates the application of radioactive tracer technique to assess the performance of industrial grade strongly basic anion exchange resins Indion-820 and Indion -930A. The radiotracer isotopes 131I and 82 Br in aqueous form were used to trace the ion-isotopic exchange reaction kinetics under different operating conditions like temperature and concentration of ionic solution. It is observed that the specific reaction rate (min-1), percentage of ion exchange, and distribution coefficient values calculated for Indion-930A are higher than that calculated for Indion-820. It is expected that the radioactive tracer technique as used in the present investigation can be applied to evaluate the performance of different resins which are synthesized and tailor made for their specific technical applications.
