FIELD: waste treatment.
SUBSTANCE: invention relates to methods for obtaining biosorbents. A method for obtaining biosorbents with specified properties based on agricultural waste is described, including pyrolysis of organic residues with cyclic loading of raw materials, carried out to a set temperature with a given temperature gradient and holding time, followed by reactor cooling and extraction of sorbent samples, with pre-drying performed at a temperature of 150°C for 30 minutes, and pyrolysis for each portion of the raw material was carried out at a temperature rising from 150°C to the set values selected from 300°C, 500°C, 700°C, 900°C, with a heating rate, selected from 5, 10, 15, 20, 25°C/min, and the exposure time selected from 15, 30, 45, 60, 75 minutes.
EFFECT: creation of a safe method for obtaining biosorbents with specified properties based on agricultural waste.
