FIELD: chemistry.
SUBSTANCE: invention refers to technical chemistry, specifically by demercuration of surfaces contaminated by spilled metal mercury. Method consists in mechanical removal of mercury drops with thereafter applied aqueous demercurator solution kept on the surface. Said demercurator is 10-15% aqueous solution of ammonium perchlorate containing 10% ammonium chloride in 100 grams. Demercuration time is at least 2 hours at temperature within +4°C to -10°C.
EFFECT: method allows reducing demercuration time and improving process efficiency, and also ensures lower damage of the processed surface.
