ABSTRACT:
Photocatalysis has been predicted as a promising technology for waste water treatment. Bismuth oxide has been used as effective photocatalyst for carrying out number of chemical reactions. The photocatalytic bleaching of malachite green was carried out in the presence of semiconducting Bismuth oxide 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 of the dye was observed. A tentative mechanism has been proposed for the photocatalytic bleaching of dye.
