In this experiment, sunlight was used as the source for UV irradiation and titanium dioxide, TiO2 as catalyst. The effects of some process variables on decolorization such as amount of TiO2, azo dye concentration and dosage of hydrogen peroxide (H2O2) were examined. TiO2-based photocatalytic degradation is an effective, economic and faster mode of removing azo dye AO7 from aqueous solution. The presence of sunlight enhanced the decolorization rate of AO7 and mineralized the intermediate products completely. The mineralization of AO7 was supported by the UV-Vis and ion chromatography analysis. The addition of proper amount of H2O2 could optimize the decolorization rate of AO7. The photocatalytic degradation of AO7 followed first-order kinetic model. 2013-12-31T08:33:32Z 2013-12-31T08:33:32Z 2012 Article Desalination and Water Treatment, vol. 48(1-3), 2012, pages 245-251 1944-3994 http://www.tandfonline.com/doi/abs/10.1080/19443994.2012.698820#.UsJ-eNIW2yo http://hdl.handle.net/123456789/30916 en Desalination Publications
