“…[1][2][3][4] Many kinds of anion-exchange groups added onto the surfaces of matrix polymers, such as quaternary ammonium groups or primary to tertiary amino groups, produce different selectivity for anions. 5,6 All of the techniques used for preparation of anionexchange materials are both costly and time consuming because indirect and complex processes, including the polymerization of monomers and subsequent chemical modifications, are required for the introduction of anion-exchange functional groups into the polymer chains.…”

Vinyl benzyl trimethyl ammonium chloride (VBTAC) could be efficiently and stably grafted onto polyester fiber coated with a surfactant polyester (PET) by a photoirradiation-induced graft polymerization with benzophenone as the photoinitiator without any cografting monomer required. The degree of VBTAC grafting could be controlled simply by the irradiation time and concentration of VBTAC in the monomer solution. The anion-exchange capacity (AEC) of the PET-g-VBTAC fabrics increased with increasing degree of grafting up to 80 6 5% and then leveled off. The maximum AEC of PET-g-VBTAC was 2.2 mequiv/g; this was similar to that of a commercial anion-exchange resin (2.16 6 0.04 mequiv/g) and much higher than those of nylon-g-VBTAC-2-hydroxyethyl methacrylate fabrics ( 1.0 mequiv/g) prepared with a conventional cografting system. The grafted fabric was characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy studies, and the sorption selectivity for anions and regeneration efficiency were estimated. The results suggest that the grafting system, in which VBTAC alone was grafted onto PET fiber coated with surfactant, was more practical and effective for the preparation of the VBTACcontaining anion exchanger, and the resulting PET-g-VBTAC fabrics could be used as an effective anion exchanger.

“…To handle excess phosphate discharge, the removal of phosphate employing various technologies has been investigated using physical (Clark et al, 1997;Omoike and Vanloon, 1999), chemical (Ruixia et al, 2002) and biological (Stensel, 1991) . Beginning in 2012, the maximum discharge limit of total phosphorous in Korea was tightened from 2.0 to 0.2 mg/L.…”

:The removal of phosphate from surface water is becoming increasingly vital to prevent problems such as eutrophication, particularly near urban areas. Recent requirements to reduce high concentrations of phosphate rely on physicochemical methods and adsorbents that must be effective even under strict conditions. The phosphate removal efficiencies of two adsorbents, Fe-Mn-Si oxide and Fe-Mn oxide, were investigated and the data used to compare kinetics and isotherm models. The maximum adsorption capacities of the two adsorbents were 47.8 and 35.5 mg-PO 4 3-/g, respectively. Adsorptions in both cases were highly pH dependent; i.e., when the pH increased from 3 to 9, the average adsorption capacities of the two adsorbents

“…There are various knowledge were developed to decreased fluoride (F-) content in water, such as thickening and electrodialysis (Srivastava et al, 2013;, membrane operation and electrodialysis (Arda and Orhan, 2009;Dominguez and Charbit, 2005;Sunil, 2013; electrochemical treatments (Mokashi and Parlikar, 2013;Maallemi, et al, 2008;Erguna and Tora, 2008), ion-exchange and its variation (Ruxi and Hong, 2002;and Grames, 2002), moreover, the adsorption technique is the actual method for eliminating fluoride from drinking water . Recently, most of researcher targeted on fluoride (F-) removal using normal, biomass component and synthetic material such, fly ash (Piekos and Palawanska, 1999), activated alumina (Ghorai, and K., 2005), chitosan drops (Labhsetwar, et al, 2010) and red sludge (Ranjeeta and Shikha, 2013), The last study for fluoride removal has been used low cost materiel of bone char for fluoride removal (Sorlina, 2011).…”
