    Abstract: A method for regulating the distribution of metallic nanoparticles within the resin support is provided. This method uses the ion exchange or absorption resin bearing basic functional groups as the support; firstly introducing the metal in the form of anionic complexes onto the resin support through the ion exchange process, then realizing the purpose of regulating the distribution of the metal and its compound within the resin support by means of changing the concentration of the reductive or deposition agent in water solution and the reaction time. The regulated distribution of metallic nanoparticles within the resin support is in the form of rings with different depths and densities. The different distribution patterns result in improvements upon properties of the inorganic-organic composite material, such as reaction activity, reaction selectivity and metallic stability, and has significant referential value for preparation and structural regulation of other inorganic-organic composite materials of the same kind.

    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.The technical result is to introduce gem-diphosphonic functional groups by the treatment of spherically granulated cross-linked macroporous acrylonitrile-divinylbenzene copolymer with phosphorous acid, which simplifies the method for production and increases capacity and selectivity of the synthesized sorbent for indium, thus improving a complex of the application properties of the material.

    Abstract: In alternative embodiments, the invention provides processes and methods for the recovery, removal or extracting of, and subsequent purification of uranium from a wet-process phosphoric acid using a continuous ion exchange processing approach, where the uranium is recovered from a phosphoric acid, or a phos-acid feedstock using either a dual or a single stage extraction methodology. In both cases an intermediate ammonium uranyl-tricarbonate solution is formed. In alternative embodiments, in the dual cycle approach, this solution is contacted in a second continuous ion exchange system with a strong anion exchange resin then subsequently recovered as an acidic uranyl solution that is further treated to produce an intermediate uranyl peroxide compound which is ultimately calcined to produce the final uranium oxide product. In alternative embodiments, in the single cycle case, the intermediate ammonium uranyl-tricarbonate solution is evaporated to decompose the ammonium carbonate and produce an intermediate uranium carbonate/oxide solid material. These solids are digested in an acid medium, and then processed in the same manner as the secondary regeneration solution from the dual cycle process to produce an intermediate uranyl peroxide that is calcined to produce a final uranium oxide product.
