Аннотация

Samples of cerium(IV) tungstate (CeW) inorganic ion exchanger were synthesized using different Ce(IV) salts: (NH4)2Ce(NO3)6·2H2O, (NH4)4Ce(SO4)4·2H2O, and Ce(SO4)2·4H2O. The samples were characterized using FT-IR and X-ray diffraction. The adsorption behavior of 152+154Eu(III) and 60Co(II) on CeW was studied under batch and dynamic conditions. Factors influencing the adsorption kinetics were examined. Loading and elution behavior of both ions was studied using different eluents. Complete separation of Eu(III) and Co(II) (152+154Eu and 60Co tracers) was achieved using small columns packed with CeW.
