Gas Chemical Carbonization of Mercury in Industrial Wastes
Gas chemical carbonization of mercury in industrial mercury-containing wastes (construction wastes and ground) from Rosatom enterprises using carbon dioxide is considered. The thermodynamic analysis of the formation of basic carbonate of divalent mercury (HgCO 3  · 2HgO) in the interaction of mercury oxide with carbon dioxide was carried out. The influence of carbon dioxide pressure, temperature and treatment time on the effect of gas chemical carbonization of mercury oxide was studied. A technological scheme of two-step gas chemical processing of mercury-containing wastes was proposed. Biotesting of the samples of construction wastes and ground subjected to gas chemical carbonization of mercury was carried out.
