Abstract

The photocatalytic decolorization of aqueous Congo red dye (CR) solution was investigated in TiO 2 suspensions irradiated with artificial UV light. Batch photocatalytic tests were carried out by varying the amount of TiO 2 and the source of UV radiation. The doses of TiO 2 were 0.25, 0.5 and 1.0 g L -1 and the wavelengths of the incident ultraviolet light were predominantly 254 (UV-C) and 365 nm (UV-A). In the presence of TiO 2 photocatalyst, UV-A radiation showed higher degradation efficiency of CR than UV-C radiation, with less energy demand (consumption). On the other hand, UV-C radiation without TiO 2 photocatalyst was capable of degrading CR, while UV-A radiation alone did not show a potential for CR degradation. CR adsorption on the surface of TiO 2 particles is also investigated and described.
