Characterization of binary oxide photoactive material and its application for inorganic arsenic removal

Binary metal oxide beads were fabricated by using aluminum oxide (industrial waste) and titanium dioxide using boehmite as binder, as prepared material exhibited photocatalytical oxidation property and good adsorption efficiency. The synthesized beads were characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and Scanning Electron Microscopy coupled with Energy dispersive spectroscopy (SEM-EDX) to investigate the functional groups, crystalline phase and morphology of the as prepared materials. Photocatalytic oxidation of As(III) took place rapidly and followed first-order kinetics. The results indicated that as prepared composite is a promising material for As(III)and As(V) removal from arsenic-contaminated water.
