Comparative Study of Tulsion A-23 and Indion -810 Strongly Basic Anion Exchange Resins By Application of 131I as a Tracer Isotope

The present study is an interesting application of 131I radioactive tracer isotope in characterization of nuclear and non-nuclear grade ion exchange resins Tulsion A-23 and Indion -810. The resins were characterized based on the specific reaction rate (min-1), percentage and amount of iodide ion exchange (mmol) and distribution coefficient values, under identical operating conditions. It is observed that using both the resins, there exist a strong positive correlation between amount of iodide ion exchanged and concentration of iodide ion solution; while a strong negative correlation exist between amount of iodide ion exchanged and temperature of iodide ion solution. The overall results indicate the superior performance of Tulsion A-23 over Indion -810 resins. It is expected that the technique used in the present investigation can be successfully extended to access the performance of different industrial grade ion exchange resins.
