FIELD: chemistry.
SUBSTANCE: invention relates to adsorbent for purification of gases from chlorine and hydrogen chloride. Adsorbent contains in wt %: zinc oxide - 26.0-75.0; magnesium oxide - 1.5-6.0; aluminium oxide - 21-70. Method of obtaining adsorbent includes mixing initial components in medium of ammonia-carbonate solution, evaporation, drying and calcinations in non-isothermal mode with rise of temperature to 400-600°C and exposure at final temperature for 2-4 hours.
EFFECT: obtaining adsorbent with increased chlorine adsorption capacity and strength.
