Abstract:
The removal of chemical pollutants from industrial effluents and wastewater has received much attention in the last decade. Dyes are one of the main sources of water pollutants. Textile dyes and industrial dyes are large groups of organic compounds that increase environmental hazards and pollution. Photocatalytic degradation with semiconductor photocatalyst is a new, effective, rapid, and destructive method for the purpose of water and wastewater treatment. Photocatalytic removal method, unlike removal methods without degradation of molecular structure such as surface adsorption, degrades the structure of organic molecules by oxidation and recovery reaction at the catalyst surface. Titanium dioxide synthesized in this study by sol-gel method is considered as one of the best photocatalysts activated in the UV light range. In order to improve its performance, porous carbon support has been used to increase the surface area and prevent agglomeration. TiO2/C was characterized by XRD analysis which confirmed the existence of anatase phase. Photocatalytic process showed 98.5% and 99.5% removal for Methylene blue (MB) and Reactive red (RR) pollutants respectively.
