  • Patent number: 9375702
    Abstract: The invention relates to the field of ion exchange with the formation of a complex or chelate by using complex-forming polymers and can be used in nonferrous metallurgy and hydrometallurgy of indium for extraction of indium from wastewaters, as well as in the chemical industry and for producing special-purity substances. A method for producing a complex-forming sorbent for selective extraction of indium is proposed, wherein the method comprises the introduction of gem-diphosphonic functional groups, and wherein, in order to increase the selectivity and sorption capacity for indium, the gem-diphosphonic functional groups are introduced by the treatment of a spherically granulated cross-linked macroporous acrylonitrile-divinylbenzene copolymer with phosphorous acid at temperature of from 140 to 160° C. for from 13 to 35 hours. In the presence of a diluent (chlorobenzene), the method is carried out at a temperature of between 100 and 130° C.
