The complex oxides of MxMn1-xO2•nH2O composition, (M-Zr, Ti, Sn) have been synthesized. Their surface was modified with phosphoric acid. phosphoric-molybdic acid and cobalt hexacyanoferrate. The sorption isotherms of Sr2+, Cs+ ions, as well as isotherms of sorption-desorption of such radionuclides as 90Sr and 137Cs were obtained. It was found that the most suitable sorbents for Sr2+ removal are MxMn1-xO2•nH2O complex oxides. ZrO2 modified by phosphate and molybdophosphate anions is effective towards Cs+. The sorbent consisting of titanium dioxide and cobalt hexacyanoferrate can be recommended for extraction of both Sr2+ and Cs+ ions.
