    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.

    Abstract: An aqueous two-phase system (ATPS) containing a poly(oxyethylene) (POE) and a poly[sodium (diallylamino)alkylphosphonate-alt-sulfur dioxide] form a pH-responsive dianionic polyelectrolyte (DAPE). The two polymers form ATPS's at low concentrations, where the addition of HCl changes the charge types and their densities on the polymer chains.

  • Patent number: 8900492
    Abstract: A process for the preparation of thermal insulation sheets fashioned from certain unseparated mixtures of post-consumer plastic articles and the article, itself, is disclosed. The mixtures of such articles contain polyethylene terephthalate (PET) and polystyrene (PS) and optionally also articles made of high density polyethylene (HDPE). An unseparated mixture of such articles is provided. This mixture is crushed and shredded to form plastic flakes, and these plastic flakes are then homogenized. Homogenization of the flakes can be carried out either by melt-blending them or by further comminution to produce very fine particles of the mixed plastics. The resulting homogenized mixture of plastic types is then compression molded into sheets ranging in thickness from about 3 to 10 mm.

  • 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.

  • Patent number: 8871822
    Abstract: The cross-linked polyphosphonate-sulfone composition for removal of metal ions from wastewater relates to a cross-linked anionic polyelectrolyte polymer for the removal of metal ions, such as lead (Pb2+) and copper (Cu2+) ions, from wastewater and the like. The cross-linked anionic polyelectrolyte polymer has the formula: The cross-linked anionic polyelectrolyte polymer is made by cyclopolymerization of diallylaminomethylphosphonic acid, 1,1,4,4-tetraallylpiperazinium dichloride (a cross-linker), and sulfur dioxide in the presence of AIBN (an initiator) in DMSO at 65° C. to form a cross-linked polyzwitterionic acid (CPZA). The CPZA is then treated with base (such as sodium hydroxide) to form the cross-linked anionic polyelectrolyte polymer having the formula shown above.

    Abstract: An object of the present invention is to provide titanium oxide granules that have a novel structure and have a characteristic of highly efficient decomposing capability, and a method of decomposing plastic and organic waste by using the granules. The present invention has been completed based on the finding that a method of decomposing plastic waste by using titanium oxide granules having a transition metal and/or a transition metal oxide, in particular copper, supported thereon enables decomposition of plastic waste at extremely high efficiency in a low-temperature region for a long period of time as compared to methods of decomposing plastic waste by using the related-art titanium oxide granules.

  • Patent number: 8865781
    Abstract: A method of processing waste carpet or matting material to separate constituent materials thereof, includes optionally drying the material and then cooling the material to a temperature at which at least one constituent material therein is embrittled. A mechanical force is applied to the cooled material causing the embrittled constituent material to break into fragments. Optionally, the material from the previous step is dried. The material is then separated to separate the fragments of constituent material from other constituent material. The carpet material can be initially shredded into coarse pieces. The procedure may be repeated optionally with different temperatures to selectively embrittle and fragment different components and facilitate their separation.
