Abstract
Multitracer techniques have been applied to the study on adsorption behavior of such ion exchangers as amorphous and crystalline zirconium phosphates and their homologues as well as ion exchange resins by using the fission products of uranium. It was found that the distribution coefficients of many cationic radionuclides were relatively high for γ-zirconium phosphate and amorphous one. Zirconium and niobium behave uniquely, and selective sorption of barium on α-titanium phosphate was observed. Multitracer technique by use of fission products provides, at least qualitatively, useful means to elucidate simultaneously the sorption behavior of many kinds of ions under the same environment.
