Abstract

The kinetics of iodide and bromide ion-isotopic exchange reactions was studied by radio analytical technique using 131I and 82Br as tracer isotopes. The parameters like specific reaction rate (min−1), amount of ions exchanged (mmol), initial rate of ion exchange (mmol/min) and logK d were studied to evaluate the performance of nuclear and non-nuclear grade anion exchange resins Indion-103 and Indion-870. For iodide ion-isotopic exchange reactions under experimental conditions of 35.0°C, 1.000 g of ion exchange resins and 0.002 M labeled iodide ion solution, the parameters were 0.223 min−1, 0.300 mmol, 0.067 mmol/min and 18.7, respectively, for Indion-103, and those of 0.165 min−1, 0.251 mmol, 0.041 /min and 16.2, respectively, for Indion-870. The similar tendency was observed during bromide ion-isotopic exchange reactions. The results suggest that Indion-103 shows greater performance than Indion-870 resin under similar experimental conditions.
