ABSTRACT

Thermal decomposition of a volatile organic compound of radioactive iodine, methyl iodide CH3131I, in a gas flow in the presence of various modifications of “Fizkhmin”TM granulated materials based on silica gel impregnated with d-elements was studied. Under comparable experimental conditions, 97% - 99% decomposition of CH3131I is achieved at ~770?C without sorbents and at ~540?C and ~465?C in the presence of straight silica gel and of the material based on it, impregnated with compounds of Ni or its mixture with Cu (8 - 10 wt%), respectively.
