Abstract

This research is mainly focused on evaluation of ZnO as a catalyst to decolorize cibacron brilliant yellow dye in presence of sunlight. The rate of de-colorization was monitored in terms of percentage transmission using UV-Vis Spectroscopy. The effects of different operating parameters which influence the de-colorization process such as initial dye concentration and catalyst loading has been systematically investigated. From the result it was observed that de-colorization process enhanced in the presence of sunlight yielding 90% efficiency at optimized condition i.e. dye concentration of about 12ppm with catalyst dosage 0.4g for time duration of 180 minutes indicating right selection of operating parameter dosage allows in effective decolorization of cibacron brilliant yellow dye. Therefore ZnO can be effectively used as photo-catalyst which can exploit solar energy in order to improve efficiency of the photo-catalysis process.
