Radiotracers in Study of Anion Exchange Resins Purolite NRW-8000 and Duolite A-171

Radioactive tracers 131I and 82Br were used to understand the performance of anion exchange resins Purolite NRW-8000 and Duolite A-171. The ion exchangers were separately brought in equilibrium with labeled I- and Br- ions solutions in the concentrations range of 0.001 to 0.004 mol/L and temperature varying from 30.0 to 45.0°C to study the I- and Br- ion-isotopic exchange reactions. The results show that under similar experimental conditions, the values of specific reaction rate in min-1, amount of ion exchanged in mmol and initial rate of ion exchange in mmol/min were lower for Br- ion-isotopic exchange reaction as compared to that for Iion- isotopic exchange reaction. Also for both the reactions, under similar conditions, the specific reaction rate values rises with rise in concentration of ionic solution, and decreases with rise in temperature.
