Abstract:A series of hybrid membranes composed of quaternized chitosan(q-CS) and tetraethoxysilane(TEOS) were prepared by sol-gel method,taking q-CS and the TEOS as organic and inorganic component respectively.The structure of the hybrid membranes was investigated by FT-IR.The adsorption performance of the membranes for Cr(Ⅵ) ions from aqueous solution was also studied.The effect of adsorption time,the pH value of solution and temperature of the adsorption on adsorption results were studied and show that the suitable membrane is composed of 38wt% TEOS,and the optimum adsorption conditions were carried out at 35 ℃ for 180 minutes with pH value of 5.0~8.0.
Keywords:Quaternized chitosan  Tetraethoxysilane  Hybrid membrane  Cr(Ⅵ)  Adsorption
