Résumé

The characterization of organic base anion exchange resins Purolite NRW-5010 and Indion AGR was made by application of short lived radio tracer isotopes 131I and 82Br. The characterization of the two resins was based on their performance during iodide and bromide ion-isotopic reaction taking place between the resin surface and the external labeled ionic solution. The exchange reactions were carried out by using the ionic solution in the concentration range of 0.001 to 0.004 mol/L and temperature varying from 30 to 45.0°C. It was observed that during iodide ion-isotopic exchange reaction taking place at 40°C using 1.000 g of ion exchange resins and 0.003 mol/L labeled iodide ion solution, the values of specific reaction rate (min-1), amount of ion exchanged (mmol), initial rate of ion exchange (mmol/min) and log Kd were calculated as 0.251, 0.485, 0.122 and 11.4, respectively for Purolite NRW-5010 resin, which was higher than the respective values of 0.098, 0.323, 0.032 and 5.4 as obtained for Indion AGR resins. Also at a constant temperature of 40°C, as the concentration of labeled iodide ion solution increases from 0.001 to 0.004 mol/L, the percentage of iodide ions exchanged increases from 60.00 to 66.20% for Purolite NRW-5010 resins and from 41.20 to 43.80% for Indion AGR resins. The similar trend was observed for the two resins during bromide ion-isotopic exchange reaction. From the overall results it appears that as compared to Indion AGR resins, under identical experimental conditions Purolite NRW-5010 resins shows superior performance.  Keywords: Anion exchange, ion exchange resins, Purolite NRW-5010, Indion AGR, radio isotopes, 131I, 82Br, characterization, ion-isotopic exchange reactions
