  • 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: 8895633
    Abstract: The cross-linked polyaminocarboxylates for the removal of metal ions from aqueous solutions of the present invention are cross-linked anionic polyelectrolytes CAPE 6 and CAPE 9, containing pH-responsive amino acid residues. The cross-linked anionic polyelectrolytes have been synthesized via cycloco-polymerization and ter-polymerization of a diallylammonioethanoate monomer (90 mol %) and a cross-linker, 1,1,4,4-tetraallylpiperazinium dichloride (10 mol %) in the absence of SO2 (CAPE 6) and in the presence of SO2 (CAPE 9), respectively. For the sorbents CAPE 6 and CAPE 9, the efficiency of Cu2+ removal at an initial metal concentration of 200 ppb was found to be 77.5% and 99.4%, respectively. Treatment of real wastewater samples spiked with Cu2+ ions showed the excellent ability of the cross-linked anionic polyelectrolytes to adsorb metal ions.
