FIELD: chemistry.
SUBSTANCE: invention relates to production of activated carbon. Method of producing carbon includes milling straw into pieces sized 1-10 cm, carbonisation, activation with steam and cooling. Carbonisation process is carried out in steam medium in two steps: first at 450-500 °C, and then at 700-750 °C with holding after each stage for 70-90 minutes.
EFFECT: technical result is producing activated carbon, having efficiency during detoxication of soils from residues of herbicide "Zinger, SP", in which active ingredient is metsulfuron-methyl.
