The immobilize TiO2 powder were prepared by using a support material as the cast-iron sand. Surface characteristic of immobilized TiO2 were analyzed by FE-SEM. And immobilized TiO2 structure was analysed by XRD and shown to be rutile type. The immobilized TiO2 was tested to investigate its capacity to reduce color in wastewater. Dye materials used in this study were Suncion yellow H-E4RN(S. Y.) as the reactive aye and Methylene blue(M. B.) as the direct dye. The effect of 98% of the direct dye and 93% of the reactive dye were removed at the given conditions. In order to increase its photoactivity, α-Fe2O3 and WO3 were added to TiO2. There mixed TiO2 showed better color removal efficiency up to 20% than pure TiO2. It was found that mixed W, Fe those transition metal oxides and supported on the ceramic can be applied to the field application.
