Separation of fission products by ion exchange method
Description
The sequential separation of Ru-103, Cs-137 and Ce-144 was carried out by organic cation exchanger, Amberite CG-120, and inorganic ion exchangers, silica gel and montmorillonite. The optimum conditions of Ru-103, Cs-137 and Ce-144 on Amberite CG-120 are 0.01M-, 0.01M- and 0.1M-hydrochloric acid for the adsorption, and 3M-, 3M-and 5M-hydrochloric acid for the desorption, respectively. The optimum conditions of Ru-103, Cs-144 on silica gel are pH 8, pH 8 and pH 8 for the adsorption, and 3M-, 1M-and 1M-hydrochloric acid for the desorption, respectively. The optimum conditions of Ru-103, Cs-137 and Ce-144 on montmorillonite are pH 8, 0.01M-hydrochloric acid and pH 4 for adsorption, and 1M-, 5M- and 3M-hydrochloric acid for the desorption, respectively. The adsorption which occurs at lower ionic strength and the differences in desorption ionic strength are utilized for the separation of tracer mixture in continuous experiments. The individual separation of Ru-103, Cs-137 and Ce-144 can be carried out more efficiently with montmorillonite than with silica gel and Amberite CG-120. (Author)
