Abstract

An advanced oxidation process system to remove residual azo dye in water, called microwave-assisted UV (MDEL)/TiO₂/K₂S₂O₈ hybrid system, was developed and evaluated. The combinations of the component techniques led to increased decomposition rate constants, which are higher than the sum of each component technique. In particular, the decomposition rate constant obtained using the MDEL/TiO₂/K₂S₂O₈ hybrid system, which was the highest obtained in this study, was about 1.5 times larger than the sum of the rate constant obtained using the MDEL/K₂S₂O₈ system and that obtained using the MDEL/TiO₂ system.
