FIELD: adsorption purification methods. SUBSTANCE: adsorbent containing zinc and aluminum oxides is prepared by mixing zinc-containing and aluminum-containing compounds. Molding, drying at 50-150 C, and calcination at 400-650 C. Mixing is effected in presence of acetic and nitric acids in amounts 0.5-8.0% and 0.5-2.0%, respectively, based on the weight of zinc oxide. EFFECT: increased chlorine-adsorption capacity and mechanical strength. 2 cl, 1 tbl, 9 ex
