Photocatalytic Degradation of Commercially Important Dye Acid yellow 36 byCeFeO3

In present work efficiency of CeFeO3as photocatalyst for degradation of Acid yellow 36 was studied.Photocatalytic bleaching of Acidyellow36was observed spectrophotometrically.Theinfluence of variation of different reaction parameters such as concentration of dye; pH and amount ofphoto catalyst were observed.The optimum conditions for photocatalytic degradation have been established.The optimum conditions for the degradation of Acidyellow36dye have been found as dye concentration 3x10-5M, pH= 8.0 and 0.06 g/100 ml catalyst dose.The kinetics of degradation of the dye follows first order kinetics.A tentative mechanismfor degradation of dye by CeFeO3has been proposed. The presence of hydroxyl radical as an active Oxidising species has been confirmed.
