Photocatalytic Degradation of Azure B in Aqueous Solution by Calcium Oxide

Rameshwar Ameta and Priyanka Jhalora

Photocatalytic degradation of Azure B has been carried out using calcium oxide semiconductor. Effect of various parameters like pH, concentration of dyes, amount of semiconductor and light intensity has been studied on the rate of reaction. Various control experiments were carried out, which indicated that semiconductor calcium oxide played a key role in photocatalytic degradation of dye. A suitable tentative mechanism has been proposed for photocatalytic degradation of dye.
