FIELD: sorbents. SUBSTANCE: sorbent is designed to prevent release of radioactive iodide and cesium at running condition of nuclear power stations, in accident events, and also when processing fission fuel. Modified zeolite is prepared by treating metal-substituted zeolites of NaX and NaA types by acetylene in gaseous and liquid media. The thus prepared sorbent contains product of interaction of acetylene with zeolite modified by silver or copper ion exchange, carbon compound content (on conversion to C) in zeolite ranging from 0.4 to 2.0 wt %. EFFECT: increased sorption capacity. 5 tbl
