Six different samples of a new inorganic ion exchanger, cerium(IV) silicate, have been prepared under varying conditions. Ion-exchange capacity, IR, X-ray, thermogravimetry, composition, and distribution coefficients of many metal ions have been studied and discussed. Separations of Cr-III-V-v, Cu-II-Bi-III, Ti-IV-Cr-VI, and Cr-III-Cr-VI have been developed on columns of this ion exchanger.
