UV Assisted Photocatalytic degradation of Azo dye in Textile Effluent by Advanced Oxidation Processes Using TiO2 Nanoparticles

Abstract

In the present investigation the photocatalytic degradation studies of Orange G (azo dye) employing Advanced Oxidation Processes (AOP) in aqueous suspension under 8W low-pressure mercury vapor lamp irradiation is demonstrated. The optimization of various experimental parameters such as effect of catalyst concentration, effect of substrate concentration, effect of addition of H2O2 is thoroughly investigated. Additionally, the obtained results indicates that the employment of AOPs process and selection of the operational parameters led to a complete degradation and substantial dye mineralization supported by the values of the reduction in Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC) of the treated dye solution.
