FIELD: may be used in chemical and other industries where having activated carbon containing mercury compounds. SUBSTANCE: method includes precipitation of mercury on cathode from used-up activated carbon containing mercury chlorides. Catholyte and anolyte are used in the form of 0.1N solution of sodium hydroxide. In this case, chlorine liberated on anode disproportionates sodium chloride and sodium hydroxide, and activated carbon - cathode with mercury precipitating on its surface is subjected to heat treatment to separate clean mercury. EFFECT: higher degree of withdrawal of mercury and chloride ions from used-up activated carbon. 1 tbl
