FIELD: sorbents.
SUBSTANCE: invention aims at removing mercury and mercury compounds from industrial process solutions containing alkali metal hydroxides. Coal or carbon-carbon material is oxidized with hydrogen peroxide and then treated with β-diketone in a sealed vessel to remove mercury and mercurials.
EFFECT: increased purity of alkali metal hydroxides.
