Abstract:
Novel organic-inorganic hybrid membranes were prepared through sol-gel reaction of poly(vinyl alcohol) (PVA) with tetraethyl orthosilicate (TEOS) and 3-mercaptopropyltrimethoxysilane (TMPTMS). The membranes were characterized by FT-IR, SEM, EDAX and BET analysis. FTIR spectra of PVA/TEOS/TMPTMS indicate that the TMPTMS have been introduced successfully into the PVA/TEOS structure. The change in surface of the PVA/TEOS/TMPTMS in SEM image indicatesthat metal ions successfully interact with functional groups of the membrane. The results of lead, cadmium, nickel and uranium ions adsorption onto the PVA/TEOS/TMPTMS hybrid membranes with different weight percents of TEOS and TMPTMS show that the optimum weight percent of TEOS and TMPTMS are 20% and 15% ,respectively
