Photo catalytic degradation of Malachite Green has been investigated in the presence of Nb2O5 and the progress of reaction was observed spectrophotometrically. The outcome of several operational parameters like concentration of the dye, amount of photo catalyst, pH and nature of photo catalyst has been studied on degradation of malachite green. It was also study that what’s effect of addition of common cation and anion such as Na+, K+, Ca+2, Ba+2, Cl-, SO4-2 and CO3-2 It has been found that limited quantity of all metal ions increases the reaction rate to some extent. A tentative reaction and mechanism has been proposed.
