The present work assess the capability of silicon oxide (SiO2) nanoparticle and microparticle incorporated in poly (vinyl alcohol)/chitosan/silicon oxide (PVA/CS/SiO2) beads to reduce chromium (Cr) ions of Cr (VI) to Cr (III). PVA/CS/(nanoand micro)-SiO2beads were prepared through a simple drop wise method. The elemental analysis of prepared photocatalytic beads were confirmed by scanning electron microscopy-energy dispersive x-ray spectroscopy (SEM-EDX) and morphology of PVA/CS/SiO2beads before and after Cr ions reduction were observed with SEM. The reduction of chromium (Cr (VI)) ions by both of PVA/CS/(nanoand micro)-SiO2) beads, as evaluated by the reduction duration taken were studied by photocatalytic process in which factors of SiO2powders size and pH of reducing environment were varied. Photocatalytic studies revealed better performance of PVA/CS/nanoSiO2beads in compared to PVA/CS/micro-SiO2beads in Cr (VI) to Cr (III) ions reduction. Reduction Cr (VI) to Cr (III) ions by PVA/CS/nanoSiO2beads occurred in 30 minutes and 50 minutes by PVA/CS/micro-SiO2. Moreover, both PVA/CS/(nanoand micro)-SiO2showed excellent reduction of Cr (VI) ions at lower pH environment. It is thus concluded that both of PVA/CS/(nanoand micro)-SiO2beads are capable for chromium reduction in highly acidic environment in which PVA/CS/nanoSiO2beads showed better performance.
