Zusammenfassung:FIELD: sorbents. ^ SUBSTANCE: preparation of chemosorbent for use in industrial emission gas treatment processes and in gas masks comprising impregnation of activated carbon granules with nickel chloride solution, drying, heat treatment, and sizing of granules is characterized by that activated carbon, before impregnation, is heated to 40-60, impregnated product is ripened during 2-4 h at 25-35, heat treatment is carried out at 80-115 at temperature raise rate 2-5/min, amount of nickel chloride supplied is 25-35wt %, and summary pore volume in activated carbon is 0.85-1.2 cm3/g. ^ EFFECT: increased ammonia absorption capacity, which allows dimensions of industrial adsorbents and gas masks to be diminished resulting in economical effect. ^ 3 cl, 3 ex
