PHOTOCATALYTIC DEGRADATION OF BRILLIANT GREEN USING FLOWER LIKE CADMIUM COBALTITEJAYANTI SAMOTA, SURAJ SHARMA, SHIPRA BHARDWAJ AND KUMUD INTODIAAbstract The present work comprises of cadmium cobaltite Cd Co2O4 synthesized by a simple chemical precipitation method. Cobalt nitrate and Cadmium nitrate were used as precursors. Composition and structure were characterized by XRD, FESEM, EDX, UV-Vis and FT-IR analysis. Photocatalytic degradation of brilliant green was studied using cadmium cobaltite. The effect of different parameters like pH, the amount of semiconductor, concentration of brilliant green and light intensity were observed on the reaction rate. The progress of reaction was monitored spectrophotometrically and it followed pseudo first order kinetics. A tentative mechanism has been proposed for the photochemical oxidation of dye. |
