Evaluating Photo-Catalytic Application of TiO2 Nano Particles Augmented With H2O2 for Mineralization of Pharmaceutical Effluent

Darshana Bhattia, Sachin Parikh

Abstract


Interest in the photocatalytic oxidation of non biodegradable organics from contaminated wastewater is growing rapidly. The photocatalytic activity of TiO2 nano particles synthesized via Sol-Gel method for the degradation of pharmaceutical effluent under UV light was discussed in this study. The TiO2 nano particles were characterized by X-Ray Diffraction (XRD) to determine size, Morphology Index, Specific Surface area and surface to volume ratio. The XRD results revealed that the TiO2 was composed of average size 12.96 nm. The treatment scheme involves charcoal adsorption and filtration prior to photocatalytic oxidation with TiO2 nano particles, H2O2 addition and Simultaneous aeration. Effect of various parameters like pH, Catalyst dosage and H2O2 concentration were studied to determine optimum conditions. Keywords: TiO2 nano particles; X-ray Diffraction; Adsorption; Sol-Gel method; Photo-Catalytic Oxidation
