“…Separation by adsorption is considered an effective and cost efficient method for heavy metal treatment. The adsorption by cross-linked polymers possesses illustrated is very easy to manipulate by design and experimentally due to its ability for regeneration [5][6][7][8][9][10][11][12]. Adsorption is a solid method for the removal of low concentrations of organic compounds from large volumes of potable water, process effluents, wastewater and aqueous solutions.…”

In the current study, the removal of Orange 2G dye founded in aqueous solutions using titanium dioxide-based nanoparticles has been investigated. Titanium dioxide nanoparticles were successfully prepared using tetrabutyl ammonium bromide (TTAB) as a surfactant by sol-gel method and characterized by X-ray diffraction, BET surface area, IR and TEM spectroscopy. The experimental data is most fitting with Freundlich isotherm model indicating heterogeneity of sorbent surface. Langmuir data revealed that the maximum removal capacity of Orange 2G equals to 85.47 mg g -1 . Kinetic studies disclosed that intraparticle diffusion is not the only rate-determining step and the removal process is organized by a chemical reaction as well.

“…Apparently, the preparation of chloroacetylated PS should be developed greatly. Bozena [6] prepared the chloroacetylation or bromoacetylation of St/DVB copolymer, which was used for introduction of amino groups. Yang [7] investigated the introduction of functional chloride groups onto the surface of magnetic polystyrene microbeads.…”

Polystyrene (PS) was synthesized by emulsion polymerization. The linear chloroacetylated PS was prepared high effectively by Friedel-Crafts acetylation of PS using chloroacetyl chloride and anhydrous aluminium chloride as chloroacetylation reagent and catalysts, respectively. The structure of chloroacetyl group is similar to that of chloromethyl group. In this method, carcinogenic compound (chloromethyl ether etc.) was avoided and the reactions of secondary cross link and multi-substitute could be eliminated. The resultant polymers were characterized by Fourier transform infrared spectrometery (FTIR) and thermogravimetric analysis. The effects of reaction conditions on chloroacetylation were studied, and the optimum reaction conditions were obtained. Chloroacetyl group was introduced into benzene ring of PS because of the appearance of the absorption peaks at 1695cm-1 (due to C=O bonds) and 644cm-1 (due to C-Cl bonds) in the FTIR spectrum. The thermal stability of the chloroacetylated PS was decreased with increasing chloroacetyl group. Moreover, there were two decomposing stages. The glass transition temperature of chloroacetylated PS increased with substitution value increasing. The effects of the reaction conditions such as reaction temperature, the solvent amount and the concentration of chloroacetyl chloride and anhydrous aluminium chloride on the chloroacetylation of PS were obvious. The certain loading can be controlled when it is lower than the maximum loading of chloroacetylated PS. The reaction condition is gentle and the operation is safe, simple and economical so that Friedel-Crafts acetylation of PS is an ideal reaction method.
