“…Among all the approaches proposed, adsorption is one of the most popular methods and is currently considered as an effective, efficient, and economic method for water purification. The adsorbents used include activated carbon (Nouri et al, 2002;Pereira et al, 2003), clay minerals (Celis et al, 2000;Abollino et al, 2003), zeolites (Oliveira et al, 2004), metal oxides (Wu et al, , 2005Zhang et al, 2007a), agricultural wastes (Robinson et al, 2002), biomass (Loukidou et al, 2003) and polymeric materials (Atia et al,2003).…”

As an effective, efficient, and economic approach for water purification, adsorbents and adsorption processes have been widely studied and applied in different aspects for a long time. In the recent years, a lot of novel adsorption processes have been developed for enhancing the efficiency of removing the organic and inorganic contaminants from water. This article reviews some new adsorbents and advanced adsorption methods that specialize in their compositions, structures, functions, and characteristics used in water treatment. The review emphasizes adsorption/catalytic oxidation process, adsorption/catalytic reduction process, adsorption coupled with redox process, biomimetic sorbent and its sorption behaviors of POPs, and modified adsorbents and their water purification efficiency.

“…However, there are few data regarding chelating properties of such obtained materials. In papers by Atia et al [27] as well as Senkal and Bicak [28] the poly(GMA-co-EGDMA) polymers modified among over by diethylenetriamine were used. They found that the sorption capacity for Ca(II) and Mg(II) depends on the type of the ligand and was the highest for DETA.…”

Abstract. This paper presents the synthesis, physicochemical properties and modifications of 2-hydroxyethyl methacrylate copolymers. It describes the new 2-hydroxyethyl methacrylate hydrogels in the form of microbeads of different degrees of crosslinking (2, 5, 8, 10, 15 and 20% mol). As crosslinking monomers bis[4(2-hydroxy-3-methacryloyloxypropoxy) phenyl]-sulfide and ethylene glycol dimethacrylate were used. The new hydrogels were obtained by two alternative methods in a suspension copolymerisation procedure. The copolymers were modified with diethylenetriamine in an epoxide opening reaction. Thermal properties (differential scanning calorimetry, thermogravimetric analysis) and swelling characteristic in typical solvents of the obtained functional hydrogels were examined. The chemical structure of the copolymers before and after modification was confirmed by Fourier transform infrared spectroscopy and elemental analyses. Moreover, their sorptive properties in removal of Cu(II), Zn(II), Cd(II), and Pb(II) ions from aqueous solutions were also presented. The Langmuir and Freundlich isotherm models are used to describe the adsorption characteristics of the selected modified hydrogels.

“…In previous studies, polyglycidyl methacrylatedivinyl benzene copolymer functionalized with ethylenediamine was used to adsorb Cu(II) and Pb(II) from their aqueous solutions. 23 Also, the selective removal of Cu(II) and Pb(II) ions from aqueous solutions by a diethylenetriamine functionalized polyglycidyl methacrylate-trimethylolpropane trimethacrylate copolymer was maintaned. 24 The aim of this study was to synthesize a new functional co-polymer, namely 3-chloro-2-hydroxypropyl methacrylateethylene glycole dimethacrylate, modified with tris(2-aminoethyl) amine, and to use it as a sorbent for the separation/ enrichment of lead and cadmium prior to their determination by flame atomic absorption spectrometry.…”
