摘要：Dye house effluents of textile industries leads to severe environmental problems when disposed to aquatic bodies without proper treatment. T his work was carried out to optimize the Photo - Fenton process for decolorization and mineralization of a commercial textile dye, Reactive Blue 222. The effect of different process parameters on decolorization efficiency of Photo - Fenton process was investig ated. The optimal conditions for process were observed as; pH level 3 .5, H 2 O 2 concentration 1× 10 - 2 M, FeSO 4 concentration 3.5 × 10 - 5 mol L - 1 , temperature 50 .C and process time 50 min . The maximum 95% dye decolorization was achieved along with a significant ( P < 0.05) reduction of chemical oxygen demand and total organic. The degradation products were characterized by UV – visible and FTIR spectral techniques. The results provide evidence that Photo - Fenton process was able to oxidize and mineralize the selected azo dye into non - toxic metabolites
