This research investigated the photocatalytic decolorization and degradation of an azo dye, reactive red 198 (RR198), in an aqueous solution with TiO2-P25 (Degussa) as the photocatalyst in a slurry form using UV light. There was a significant difference in the adsorption of the dye on the TiO2 surface with the change in the solution pH. The effect of various parameters such as catalyst loading, pH and the initial concentration of the dye on decolorization and degradation were determined. Thefatcat:ulzdy7qc7zfxzlolgeqvk7xiy4
