Comparative Study of Indion-810 and Indion -454 Strongly Basic Anion Exchange Resins by Application of ¹³¹I and ⁸² Br as a Tracer Isotopes

摘要

The present investigation deals with application of radiotracer isotopes ¹³¹I and ⁸²Br for performance assessment of industrial grade strongly basic anion exchange resins Indion-810 and Indion -454. The study reveals the higher percentage of ions exchanged by Indion -454 resins as compared to Indion-810 under identical experimental conditions. It is observed that iodide ions are exchanged at the faster rate than bromide ions; however the exchange rate decreases with rise in temperature and increases with increase in ionic concentration. The study indicates strong positive correlation between amount of ions exchanged and concentration of ionic solution, and a strong negative correlation between amount of ions exchanged and temperature of the exchanging solution.
