FIELD: polymer sorbents. SUBSTANCE: styrene and divinylbenzene-based sorbent is treated in electric discharge plasma in presence of plasma-forming gas (oxygen) at pressure 1-130 Pa. Apparatus has a tank partially filled with sorbent and provided with electrodes and fitting to be connected with vacuum pump, a voltage generator connected with electrodes, and ultra-sound-type vibrator communicating with sorbent tank. EFFECT: improved design of apparatus and modification procedure. 4 cl, 1 dwg
