Use of Lead Chromate as Photocatalyst for Degradation of Brilliant Green

The photocatalytic decolorizing of Brilliant green was carried out in the presence of semiconducting lead chromate and the progress of the reaction was observed spectrophotometrically. The effects of various operating variables like pH, concentration of dyes, amount of semiconductor and light intensity on the rate of bleaching was observed. A tentative mechanism has been proposed for the photocatalytic degradation of Brilliant green.
