Adsorption of cyanogen chloride on impregnated active carbon

The adsorption of cyanogen chloride on impregnated carbon containing copper and chromium compounds and other additives is accompanied by the formation of carbon dioxide. Presorbed water enhances the formation of carbon dioxide and decreases the desorption of cyanogen chloride. Cyanogen chloride is adsorbed irreversibly because hydrolysis takes place at a rate higher than that of desorption.
