FIELD: chemistry.
SUBSTANCE: invention relates to making sorbents. The method involves treatment of an aqueous suspension which contains bentonite clay and urea at 40-60°C while stirring with a reaction mixture which contains acrylic or methacrylic acid as a polymerisable compound and ammonium persulphate as a radical polymerisation initiator.
EFFECT: invention improves operational properties of the sorbent.
