摘要：
Samples of cerium(IV) tungstate (CeW) inorganic ion exchanger were synthesized using different Ce(IV) salts: (NH4)(2)Ce(NO3)(6)center dot 2H(2)O, (NH4)(4)Ce(SO4)(4)center dot 2H(2)O, and Ce(SO4)(2)center dot 4H(2)O. The samples were characterized using FT-IR and X-ray diffraction. The adsorption behavior of Eu152+154(III) and Co-60(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) (Eu152+154 and Co-60 tracers) was achieved using small columns packed with CeW.
