FIELD: sorbent production. SUBSTANCE: industrial activated carbon is treated with chemical reagent solutions, in particular, alkali and mineral acid solutions, treatment being carried out in the form of acid-water-alkali- water or alkali-water-acid-water cycles wherein acid is hydrogen chloride acid-water azeotrope mixture and alkali is potassium alkali solution. Activated carbon treatment temperature in all cases is maintained equal to boiling temperature of reagents and treatment is carried out in Soxhlet extractor in three-phase spouted bed mode. EFFECT: reduced waste water volume, treatment time, and increased product purity. 1 tbl, 5 ex
