FIELD: ecology, in particular composition for demercurization.
SUBSTANCE: claimed composition contains sodium thiosulfate and water. Additionally it contains potassium permanganate and nitric acid in the next ratio (wt.%): potassium permanganate 0.52-0.12; sodium thiosulfate 4-6; nitric acid 0.5-1.5; and balance: water. Method for demercurization of objects infested with mercury includes treatment with abovementioned composition for 2 h followed by washing with water. Composition of present invention makes it possible to reduce mercury and mercury vapor concentration to maximum allowable concentration or lower without corrosive and toxic effects.
EFFECT: stable demercurization effect after single treatment of objects infested with mercury.
