FIELD: chemistry.SUBSTANCE: invention relates to chemical processing of wood, in particular to a method of producing microporous carbon sorbents. Method of producing activated charcoal involves mixing milled initial or preliminary heat treated at 280-350 °C birch bark with potassium hydroxide, taken either in solid form or in form of a solution, carbonisation at 600-800 °C in argon atmosphere, washing obtained product to neutral pH and drying.EFFECT: technical result is improved sorption properties of carbon sorbent from birch bark due to improved microstructure.1 cl, 8 ex, 1 tbl |
