ABSTRACT
In this study, rice husk ash-silica/graphene oxide (RHA-SiO2/GO) nanocomposites were synthesized by the in situ method using (3-aminopropyl) triethoxysilane as a coupling agent. The obtained products were used to remove lead ions (Pb2+) from aqueous solution. Effects of SiO2GO mass ratio, contact time, pH and initial Pb2+ concentration on the adsorption capacity were studied. It was found that the suitable ratio of SiO2GO for Pb2+ adsorption is 1002. The suitable RHA-SiO2/GO was characterized by Fourier-transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, Brunauer-Emmett-Teller specific surface area and thermal gravimetric analysis. Accordingly, RHA-SiO2/GO nanocomposite could be used as promising adsorbent for the removal of Pb2+ from water.
