FIELD: extraction of agents with the use of sorbents; ferrous and non-ferrous metallurgy; cleaning of industrial and domestic runoff.
SUBSTANCE: proposed method consists in sorption of manganese ions from aqueous solution. Sorption process is carried out on activated coal which is subjected to preliminary treatment with acid, alkali or water. Sorption is performed at pH=2-3 after preliminary treatment with acid or alkali and at pH=2-5 after treatment with water. Sorption with activated coal is prompt and effective method of extraction of ions of manganese (VII) from aqueous solutions.
EFFECT: enhanced efficiency.
