The photocatalytic degradation of a commercial azo-reactive textile dye, Remazol Red F-3B, has been investigated in a batch slurry reactor using semiconductor catalysts like, ZnO and TiO2, and two UV sources emitting mainly at 254 and 365 rim. Non-irradiated catalysts and non-catalyzed UV irradiation have negligible effect on the dye degradation. Initial pH. dye concentration, light power and catalyst loading as well as the catalyst type and UV wavelength are considered as process variables. The results showed that decolorization and TOC removal efficiencies of ZnO are higher under 365 nm UV. On the other hand, when two photocatalysts are compared, the decolorization performance of ZnO is higher than TiO2 under 365 nm UV. while TiO2 performs better under 254 nm UV. Furthermore, from the TOC removal point, TiO2 performs better than ZnO irrespective of the UV wavelength. TiO2 irradiated under 254 nm UV degrades successfully both benzene and naphthalene derivatives. (C) 2007 Elsevier B.V. All rights reserved.
