Decolourization and Mineralization of Reactive Dye by UV/Fenton Process

The photochemical degradation of C. I. Reactive Blue 2 (RB2) in aqueous solution has been studied using homogeneous UV/Fenton process. The effects of applied H2O2, Fe2+ salt and RB2 concentrations at constant UV irradiation characteristics, pH and temperature were determined. By the application of 0.5 mM Fe2+ and 2.5 mM of H2O2 the complete colour removal and mineralization extent of 73.8 % were achieved. According to the colour and TOC removal, it could be suggested that the studied UV/Fenton type process appeared as a viable technique for the treatment of wastewater containing such type of reactive dyes.
