Abstract

SBA-15 (Santa Barbara Amoprhous 15) was functionalized by using three different organosilane comprised of different functional group, namely 3-aminopropyltriethoxysilane (APTES), 3-mercaptopropyltriethoxysilane (MPTS) and triethoxyvinylsilane (TEVS). Materials were characterized by using X-ray Diffractor (XRD), Fourier Transform Infrared Specrometer (FT-IR) and Field Emission Scanning Electron Microscopy (FESEM). Batch adsorption study was done to determine the effect of variable parameters, like contact time, temperature, pH and agitation towards adsorption. Adsorption was found to be highly dependent on effects of variable parameters of heavy metal ions aqueous solution. Kinetic adsorption study was carried out by using three models, namely pseudo first order, pseudo second order and intraparticle diffusion. Adsorption rate was found to be fast and well presented by using pseudo second order.
