ABSTRACT
Environmental pollution is a big problem, which we all are facing today. Out of which, water pollution is a major problem. Different technologies of advanced oxidation processes are playing important role in solving this problem. Photocatalysis, which is an important part of advanced oxidation process, is considered as a promising technology for waste water treatment. In the present investigation, the photocatalytic degradation of toluidine blue-O (TB) has been studied using molybdenum doped titanium dioxide. The progress of the reaction was observed spectrophotometrically. The conditions for optimum degradation rate of the dye were achieved. It was observed that degradation of the dye follows pseudo-first order kinetics.
