Photo Catalytic Applications of Nanoparticles

The decontamination activity of nanoparticles on pesticide residues (acylamino acid class fungicide of benalaxyl, strobilurin fungicides of azoxystrobin and Pyraclostrobin, conazole fungicides of epoxiconazole, tetraconazole and unclassified fungicide of tricyclazole in water was investigated. The decontamination of the pesticide residues was studied in Milli-Q water, pH 4, pH 7 and pH 9 buffer solutions under sunlight in natural climatic conditions. Kinetic parameters such as rate constant (k), DT50 and DT90 were calculated using the dissipation data of all pesticides.The reaction rate follows first order and the degradation was high in pH 9 buffer water for epoxiconazole, tetraconazole and Tricyclazole and benalaxyl when compared to Milli-Q water and other buffer solutions, the degradation order was
