Abstract

The trapping of methyl iodide from flowing humid air by impregnated charcoals was studied with regard to chemical reactions between methyl iodide and impregnants. Twenty-seven compounds for impregnation on activated charcoal were tested. Stannous iodide and potassium thiocyanate were found to be the most effective, as well as potassium iodide and riethylenediamine, for the removal of methyl iodide in flowing steam-air systems. The characteristics of the base material for impregnation and the surface properties of the impregnated charcoals are also discussed.
