Preparation method of ammonia-free impregnated carbon for protecting CNCl and HCN impregnated copper glycinate

The invention discloses a preparation method of ammonia-free impregnated carbon for protecting CNCl and HCN impregnated copper glycinate, and relates to the technical field of adsorption material preparation, and the preparation method comprises the following steps: a, measuring the water capacity of to-be-impregnated activated carbon, calculating to obtain the use amount of deionized water, heating, stirring and dissolving to obtain an activated carbon solution; raising the temperature of the solution to 50-100 DEG C to obtain a copper glycinate water solvent system steeping liquor; b, adding activated carbon to be impregnated, and standing to enable the activated carbon to fully and uniformly absorb the copper glycinate; c, carrying out heat treatment activation on the impregnated activated carbon for 2-12 hours at the temperature of 100-200 DEG C; and d, cooling to obtain the ammonia-free impregnated carbon for protecting the CNCl and HCN impregnated copper glycinate. Inspection proves that the prepared ac
