FIELD: chemistry.
SUBSTANCE: method of obtaining granular activated carbon includes milling a coal raw material, mixing it with a resin binding agent and doping additive, granulation of the composition, cooling the granules, carbonisation and steam-gas activation. As the doping additive into the carbon-resin composition introduced is tristrimethylsiloxyphenylsilane.
EFFECT: invention makes it possible to obtain granulated activated carbon with the high absorption ability, recommended for the extraction from sewage and return waters of flotation factories of residues of flotation agents, such as potassium xanthogenate.
