SORBENT FOR ENTRAPPING RADIOACTIVE IODINE FROM GAS PHASE

摘要

FIELD: nuclear-industry radiochemical enterprises for recovering and immobilizing gaseous radioactive wastes. ^ SUBSTANCE: sorbent used for entrapping radioactive iodine from gas-aerosol stream running from irradiated nuclear fuel cutting-and-dissolving unit has porous base impregnated with nitric acid silver salt (AgNO3); used as sorbent base is porous silicon carbide of 30 to 60% porosity. ^ EFFECT: enhanced corrosion and mechanical resistance of material in chemically active media. ^ 1 cl, 2 dwg, 3 tbl
