  • Patent number: 9486799
    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.

  • Patent number: 9120093
    Abstract: Polymeric anion exchanger are used as host materials in which sub-micron sized hydrated Zr(IV) oxides (HZrO) particles are irreversibly dispersed within the ion exchange medium, such as beads or fibers. The HZrO can be impregnated into the pore structure of resin by mixing the parent anion exchange resin with zirconium solution prepared by pre-calcined zirconium oxide dissolved in concentrated mixture of alcohol and acid, and then followed by precipitation of HZrO particles within the resin by using alkaline solution. Since the anion exchangers have positively charged such as quaternary ammonium functional groups, anionic ligands such as arsenate, fluoride can transport in and out of the gel phase without subjected to the Donnan exclusion effect. Consequently, anion exchanger-supported HZrO submicron particles exhibit significantly greater capacity to remove arsenic and fluoride in comparison with parent anon exchange resins.

  • Patent number: 8937104
    Abstract: The cross-linked polyzwitterion/anion for the removal of strontium from aqueous solutions is a polyzwitterion having the following structure: and the corresponding anion formed by treating the polyzwitterion with a base, e.g., sodium hydroxide. The cross-linked polyzwitterion/anion (CPZA) was prepared using Butler's cyclopolymerization protocol. The CPZA resin was found to have a very good adsorption capacity for Sr2+ ions at low concentrations. The relatively strong rapid initial adsorption of 83% Sr2+ ions was followed by slower adsorption of the remaining 17%, which was described by an intraparticle diffusion model. The adsorption followed the Lagergren second-order kinetic model, and Temkin as well as Freundlich isotherm models. The negative ?Gs and ?H ensured the spontaneity and the exothermic nature of the adsorption process. The excellent adsorption and desorption efficiencies implied the efficacy of the resin in removing (as well as recovering) the metal ions from aqueous solution.

  • Patent number: 8519014
    Abstract: An ion exchangeable mixture containing a polymeric compound consisting of an ion exchange resin, an acrylamide mixture containing at least one bisacrylamide and at least one acrylamide, and a copolymer obtained by reacting the polymeric compound with the acrylamide mixture, and a method of producing the same are provided. The ion exchangeable membrane produced by using the ion exchangeable mixture has significantly smaller electric resistance than conventional ion exchangeable membranes, and has excellent selective permeability because the ion exchangeable membrane is electrically charged. The ion exchangeable membrane can be produced under very mild production conditions, and thus can be produced very easily. Furthermore, the ion exchangeable membrane can be also formed into film during a crosslinking reaction in a solvent of water, and thus is advantageous in that the ion exchangeable membrane can be freely produced into desired sizes, shapes and forms.
