Chromatographic separation of heat-generating nuclides <SUP>90</SUP>Sr and <SUP>137</SUP>Cs from high-level liquid wastes has been studied by means of column packed with inorganic ion-exchangers. The distribution coefficients (K<SUB>d</SUB>) of Sr<SUP>2+</SUP> and Cs+ onto zeolites decreased with increasing concentrations of monovalent cations. The retention volumes (V<SUB>R</SUB>) with a 2M (=mol/dm<SUP>3</SUP>) NH<SUB>4</SUB>Cl solution decreased in the order, natural mordenite (NM) ?? chabazite>clinoptilolite for Cs+, and titanic acid ?? zeolite Y for Sr<SUP>2+</SUP>. The column containing mixtures of Y and NM was effective for selective adsorption of Sr<SUP>2+</SUP> and Cs<SUP>+</SUP> from a simulated waste solution, and chromatographic separation of these adsorbed nuclides was accomplished by passing a 2<SUB>M</SUB> NH<SUB>4</SUB>Cl solution through the column of mixing ratio of Y:NM=3:2.
