Water is the most essential natural resource for living beings, animals and plants but unfortunately it is being polluted by various means. Coloured pollutants, mainly dyes contribute maximum to this. Thus an attempt is made to remove such pollutants in an eco friendly manner. Novel nano sized composite material ZrCdPbO4 is synthesized by coprecipitation method, characterized by UV-vis, IR, FESEM, XRD, XPS and EDX analysis methods and is used for removing such pollutants from water. The emphasis of the present work is to use the prepared material as photocatalyst for degradation of various pollutants. Experimental details of degradation of a common industrial effluent, Azure-A dye as role model are discussed. Number of factors are varied to obtain maximum degradation rate through pseudo first order kinetic study. Hydroxyl radicals are found to play important role in cleavage of various bonds of the pollutant and is endorsed by scavenger study. LCMS/MS analysis is carried to rule out the route of the degradation. Final products are ascertained by laboratory tests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
