Different methods are utilized for degradation of organic pollutants in treating effluents of various industries. Photocatalysis is an advanced oxidation technology for wastewater treatment. The present work presents the degradation of azure A by C-doped TiO 2 , a nanophotocatalyst prepared by sol-gel method. Th e effect of various rate-affecting parameters are monitored spectrophotometrically. A tentative mechanism has been proposed based on experimental observations. The kinetic study of this system reveals that this reaction follows pseudo-first order kinetics.
