Abstract


The ion exchange sorption of Cs+ and Sr2+ on clinoptilolite (CL) from deposit of Armenia in initial, modified by e- and g-irradiation, decationated with a hydrochloric acid, and cation-contained forms was studied. On the basis of received data the exchange capacity Е for Sr2+ and Cs+,distribution factor Кd, sorption factor Кs were determined. It was shown that untreated CL(Ar), decationated CL(Ar)H and Ca-containing forms are characterized by a big ion exchange activity on strontium and cesium to compare with irradiated samples and the most perspective ion exchange sorbents for these ions are CL samples modified by a chemical way.
