The color and chemical oxygen demand arising from Acid Blue I, Rhodamine B and textile industry wastewater containing vinyl sulphone-based reactive dye are treated using TiO,/ UV technique. Color is found to be removed substantially during first one hour of irradiation of Acid Blue I and Rhodamine B systems. The rate of color removal from textile dyeing industry wastewater in an order of magnitude lower than that of Acid Blue I and Rhodamine B. Simultaneously, the overall COO removal efficiencies under aerated condition are found to be 60% for Acid Blue I/ TiO in 2 hours, 90 % for Rhodamine B/TiO, in 4-5 hours and 45 % for wastewater/ TiO, in 3' hours. The supplied air is found to enhance rate of color and COD removals. The results suggested that some stable intermediates are formed during phoooxidation of these dyes and the photocatalytic degradation of reactive dye containing wastewater is relatively slower.
