  • Patent number: 11000844
    Abstract: Ion exchange resin macroporous beads for the highly selective extraction of univalent anions from aqueous solutions. A specific example is the removal of dicyanoaurate and dicyanoargentate from cyanide leach solutions and tailings. The beads have a maximum number of ligands specific for the desired univalent anion, while maintaining sufficient separation to minimize binding of polyvalent ions. The beads are prepared using a functionalized monomer with the use of a specifically tuned coordinator. The beads can be used as a sensor for detecting the amount of anions captured when interrogated by an appropriate light source.

  • Patent number: 9950319
    Abstract: The present disclosed are a high exchange-capacity anion exchange resin with dual functional-groups and method of synthesis thereof. The invention relates to the field of environmental function material synthesis and application. The resin is based on chloromethylated polystyrene-divinylbenzene polymer as matrix, and by primary amination and quaternization, yields an anion exchange resin with dual functional-groups having both a weak base anionic group and a strong base anionic group. The anion exchange resin not only has high adsorption capacity for water-born nitrate ions, but also can effectively squelch natural organic acids such as phytic acid in water, thus simultaneously removing nitrate ions and phytic acid organic matter from water. Therefore, the resin has a broad application potential in the fields of drinking water treatment, groundwater remediation, and advanced urban sewage treatment.

  • Publication number: 20140069870
    Abstract: Treatment of anion exchange materials containing hydroxyl containing moieties in the beta position relative to the quaternary center in the hydroxide form with glycidol substantially alters the selectivity of the anion exchange material. Furthermore, sequential treatments of first a hydroxide containing solution to put the anion exchange material in the hydroxide form followed by treatment with glycidol in an alternating sequence progressively changes selectivity in a predictable manner allowing facile manipulation of selectivity. Unique to the selectivities achievable with this chemistry is the ability to reverse the elution order of sulfate and carbonate. With all other known systems, carbonate elutes ahead of sulfate and sometimes compromises the ability to quantitate sulfate. With glycidol treatment, carbonate can be moved after sulfate which eliminates interference issues for samples containing significantly more carbonate than sulfate.

    Abstract: The invention provides a tetrazole-containing polymer of intrinsic microporosity comprising (10) or more subunits, wherein one or more of the subunits comprise one or more tetrazolyl moieties. In one embodiment, a polymer of intrinsic microporosity (PIM-1) was modified using a “click chemistry” [2+3] cycloaddition reaction with sodium azide and zinc chloride to yield new PIMs containing tetrazole units. Polymers of the present invention are useful as high-performance materials for membrane-based gas separation, materials for ion exchange resins, materials for chelating resins, materials for superabsorbents, materials for ion conductive matrixes, materials for catalyst supports or materials for nanoparticle stabilizers.

  • Patent number: 8592493
    Abstract: Articles that contain a solid support with a grafted chain extending from the solid support, methods of making these articles, and various uses of the articles are described. More specifically, the grafted chain has a functional group that can react with or interact with target compound. Alternatively, the functional group on the grafted chain can react with a modifying agent to provide another group that can react with or interact with the target compound. The grafted chains are attached to the solid support through a ring-opened azlactone group. The articles can be used to purify the target compound or to separate the target compound from other molecules in a sample.

  • Publication number: 20130260319
    Abstract: A method of producing a polymeric compound having a structural unit that is decomposed and generates acid upon exposure, including reacting a first precursor polymer having a first ammonium cation with an amine whose conjugate acid has an acid dissociation constant (pKa) larger than that of the first ammonium cation to obtain a second precursor polymer having a second ammonium cation that is a conjugate acid of the amine; and performing a salt-exchange between the second precursor polymer and a sulfonium cation or an iodonium cation, in which the second ammonium cation is less hydrophobic than the first ammonium cation, and also less hydrophobic than the sulfonium cation or the iodonium cation.

  • Patent number: 8476324
    Abstract: A method for manufacturing an anion exchange resin, in which remaining of impurities and generation of decomposition products are suppressed and leachables are reduced, the method including the following steps (1-a) to (1-e) of: (1-a) obtaining a cross-linked copolymer by copolymerizing a monovinyl aromatic monomer and a cross-linkable aromatic monomer; (1-b) specifying the content of a specific leachable compound to be 400 ?g or less relative to 1 g of the cross-linked copolymer; (1-c) haloalkylating the cross-linked copolymer so as to introduce 80 percent by mole or less of haloalkyl group relative to the monovinyl aromatic monomer; (1-d) removing a specific leachable compound from the haloalkylated cross-linked copolymer; and (1-e) subjecting the haloalkylated cross-linked copolymer to a reaction with an amine compound.
