Abstract

1. Способ иммобилизации ртути в твердых отходах, содержащих оксид ртути и металлическую ртуть, включающий окисление металлической ртути водным раствором перекиси водорода и осаждение ртути в виде основного карбоната 2-х валентной ртути (HgCO·2HgO), отличающийся тем, что осаждение ртути одновременно или последовательно с окислением металлической ртути проводят путем обработки углекислым газом.2. Способ по п.1, отличающийся тем, что иммобилизацию ртути в твердых отходах, содержащих оксид ртути и металлическую ртуть, проводят при давлении углекислого газа 15-20 атм.3. Способ по п.1, отличающийся тем, что иммобилизацию ртути в твердых отходах, содержащих оксид ртути и металлическую ртуть, проводят при температуре 40-50°С.4. Способ по п.1, отличающийся тем, что иммобилизацию ртути в твердых отходах, содержащих оксид ртути и металлическую ртуть, проводят в течение 4-5 часов.1. A method for the immobilization of mercury in solid waste containing mercury oxide and metallic mercury, including the oxidation of metallic mercury with an aqueous solution of hydrogen peroxide and the precipitation of mercury in the form of basic carbonate of 2-valent mercury (HgCO · 2HgO), characterized in that the precipitation of mercury simultaneously or sequentially with the oxidation of metallic mercury is carried out by treatment with carbon dioxide. 2. The method according to claim 1, characterized in that the immobilization of mercury in solid waste containing mercury oxide and metallic mercury is carried out at a carbon dioxide pressure of 15-20 atm. The method according to claim 1, characterized in that the immobilization of mercury in solid waste containing mercury oxide and metallic mercury is carried out at a temperature of 40-50 ° C. The method according to claim 1, characterized in that the immobilization of mercury in solid waste containing mercury oxide and metallic mercury is carried out for 4-5 hours.
