FIELD: chemistry.
SUBSTANCE: disclosed is a method of producing activated charcoal, which comprises crushing rapeseed straw into 1-10 cm pieces, carbonising the straw in an inert atmosphere at temperature of 450-500°C while raising temperature at a rate of 1-20°C/min and holding at final temperature for 30-60 minutes. Activation is then carried out with steam at temperature of 820-850°C, which is fed at a rate of 3-5 kg per kg of the carbonised product. Resorcinol capacity is 0.0030-0.0050 mg/g and hydroquinone capacity is 0.0040-0.0050 mg/g.
EFFECT: obtaining powdered activated charcoal with high adsorption capacity for polyphenols.
