Abstract: Photocatalysed degradation of victoria blue B (VBB) dye has been studied in aqueous suspension of zinc oxide using visible spectrophotometric analysis technique. Effect of Fenton like system was also studied. Complete aromatic ring destruction was ascertained by UV spectroscopic analysis. Decrease in COD and increase in CO2 and NO3- concentration indicated mineralization of dye. Zinc oxide proved potentially efficient photocatalyst for proposed visible and solar light system. However, power law model showed intricacy of degradation process.
