FIELD: cleaning of solutions and treatment of waste water. SUBSTANCE: synthesis of sorbent is effected through interaction of salt of transition metal with ferrocyanide ions on surface of particles of bentonite in medium of wine stock (wines, juices) at pH 2 to 4 in presence of gelatine and fish glue. Composition sorbent XЖ-90 thus obtained contains 1 to 10 mas. % of ferrocyanide of transition metal. Base for producing sorbent are waste materials of demetallization and clarification of wine stock. EFFECT: enhanced efficiency. 4 cl, 1 tbl
