Cerium (IV) and tin (IV) antimonates cation exchangers have been synthesized. The products were characterized by powdered X-ray diffraction, thermal analysis and infrared spectrometry. The data of the distribution coefficients showed that the selectivity decreased in the order Eu{sup 3+} > Co{sup 2+} > Sr{sup 2+} > Cs{sup +} for both materials. Besides, the drying temperature of the matrices have a profound effect on their ion exchange capacities. The effect of gamma radiation on the ion exchange behavior of the samples showed that a slight decrease of the capacity and the distribution coefficient values with increasing the absorbed dose. The irradiated CeSb has been successfully used for the quantitative separation of cesium which suggests its used in the treatment of active liquid wastes.
