METHOD AND SORPTION MATERIAL FOR TRAPPING VOLATILE FORMS OF RADIOACTIVE IODINE Russian patent published in 2001 - IPC

Abstract RU 2174722 C2

FIELD: nuclear power engineering. SUBSTANCE: method is realized by passing gas flow through carbon- or inorganic substance-based sorption material impregnated with complex compound, namely bivalent metal iodide-cyclamine and, more specifically, 1,4-diazobicyclo(2.2.2)octane-barium iodide complex. Complexes of zinc and lead iodides are also useful. EFFECT: enhanced radioactive iodine trapping efficiency and prolonged service time of cleaning systems, in particular under heavy-duty conditions (high temperatures, humidity, radiation field); increased sorption capacity; and reduced cost. 4 cl, 2 dwg, 2 tbl, 9 ex
