Abstract
In the present work efficiency of CeFeO3 as a photocatalyst for degradation of Reactive Brown 10 was studied. Photocatalytic bleaching of Reactive Brown 10 was observed spectrophotometrically. The influence of variation of different reaction parameters such as concentration of dye; pH and amount of photo catalyst were observed. The optimum conditions for photocatalytic degradation have been established. The optimum conditions for the degradation of Reactive Brown 10 dye have been found as dye concentration 3×10-5M, pH=8.0 and 0.06 g/100 ml catalyst dose. The kinetics of degradation of the dye follows first order kinetics. A tentative mechanism for degradation of dye by CeFeO3 has been proposed. The presence of hydroxyl radical as an active oxidising species has been confirmed.
