Example, to 1 00 g poristogs. copolymer of methyl acrylate with 7% diviylbenoolp with granules of 0.3-1.0 mm in size, 1200 ml of water, 315 g of hydroxyamine hydrochloride acid and gradually added to 12 hours 240 g of caustic nbgr are added. The mixture is heated until maintain 24 hours. The cooled product is transferred to a Büchner funnel, the granules are separated from the mother liquor and washed successively with water, hydrochloric acid and again with water until the actual reaction of the washing water according to methyl orange,

The anion exchanger obtained according to the proposed; j.iOco5y, mo :: st to be used; in the gkdroms-tollurgichesky process during the purification of copper - ;;; incine solutions from iron.

The synthesized anion exchange resin is examined in a model solution containing (in g / l) Cu. - 1.06 In - 1.03:
