Application of radioactive tracer technique on industrial grade ion exchange resins Indion-830 (Type-1) and Indion N-IP (Type-2)

Abstract

The radioactive 131I was used as a tracer to study the kinetics of iodide ion-isotopic exchange reactions. The experiment was performed to study the effect of temperature, concentration of ionic solution, and amount of ion exchange resin on kinetics of exchange reactions. It was observed that under different experimental conditions, the initial rate and the amount of iodide ions exchanged calculated for Indion N-IP Type-2 resin were higher than that for Indion-830 Type-1 resins. It is expected that the same technique can be employed to assess the efficiency of various ion exchangers under different operating conditions.
