Photocatalytic Degradation of Malachite Green Dye by Metal Oxide Nanoparticles - Mini Review

A wide range of hard adulterants in waste water are generated from different industries as a by-product of the organic compound. In this review, the cationic dye Malachite Green removal from wastewater by photocatalytic route by using various metal oxide nanoparticles is analysed. The effect of some specific parameters like the method of preparing the catalyst, the initial concentration of dye, the amount of nanocatalyst required for degradation, the initial pH of dye solution, type of light source used, and time of light exposure required for removal of dye were specially incorporated. Some general conclusions were made based on the pivotal analysis of literature available. With a view to reach higher removal efficiency, in an economical manner, some optimal testing conditions on degradation of these hard dyes should be carried out.
