FIELD: chemistry.
SUBSTANCE: invention relates to applied ecology and can be used to purify industrial waste water from phenols, suspended substances and surfactants, heavy metal ions and oil products. The method of producing sorbtion material involves treating sawdust with 4.5-5.5% orthophosphoric acid solution, washing with distilled water, mixing bentonite clay, water and treated sawdust in ratio of 1:2:2, drying the obtained mixture at temperature 80-85°C, grinding to obtain a 3-15 mm fraction and heat treatment at temperature 90-95°C.
EFFECT: invention enables to obtain an effective sorbent with high mechanical strength.
