FIELD: chemistry.
SUBSTANCE: invention relates to methods of producing sorbents from vegetable raw material. Method of producing sorbent comprises treatment of pre-dried and ground sheet fall of low-temperature plasma of high-frequency discharge at pressure in discharge chamber 26.6 MPa, anode current 0.5 A and voltage 7.5 kV for 60 seconds. Plasma generating gas used is a mixture of argon with propane in weight ratio of gases 70:30. Sorbent recommended for removal of oil and oil products from water surface.
EFFECT: capacity of produced sorbent is 8 g/g, efficiency of cleaning from oil - 99 % with contact time of 5 minutes.
