FIELD: chemistry.
SUBSTANCE: invention refers to method of mercury removal from mercury-contaminated polluted alkali or alkali alcoholate spirit. Mercury-contaminated alkali or alkali alcoholate spirit is filtered through coal at first and then through inert fibrous material. Filtration is followed with introducing distillation column into solution over the bottom. Water or spirit are reduced, while mercury-depleted alkali or spirit are delivered to the column bottom.
EFFECT: lower mercury content in solutions to maximum value 3 fractions to billion.
