Characterization Study of Anion Exchange Resins Tulsion A-33 and Indion H-IP by Application of 131I and 82 Br as a Tracer Isotopes Using γ-Ray Spectrometer

The present paper deals with the application of 131 I and 82 Br radioactive tracer isotopes in characterization of strong base, nuclear grade anion exchange resin Tulsion A-33 and intermediate base, non-nuclear grade anion exchange resin Indion H-IP. The characterization study was performed by using γ-ray spectrometer having Na(I) Tl scintillation detector. The two radioactive tracer isotopes were used to trace iodide and bromide ion-isotopic exchange reactions taking place between the ion exchange resins and external ionic solution of different concentrations varying from 0.001M to 0.004 M, in the temperature range of 30.0℃ to 45.0℃. The characterization of the two resins was made by comparing the values of specific reaction rate (min-1), percentage of ions exchanged, and distribution coefficient (Kd) values. It was observed that under identical experimental conditions, above values were calculated higher for Tulsion A-33 as compared to Indion H-IP resins, indicating superior performance of Tulsion A-33. It is expected that the radioactive tracer technique as applied in the present investigation will find important role not only in characterization of various ion exchange materials, but also in optimization of various industrial process parameters so as to bring about the efficient performance of selected resin.
