Comparison of degradation reactions of Acid Yellow 61 in both oxidation processes of H2O2/UV and O3.
The comparison of degradation of Acid Yellow 61 as a model dye compound in both oxidation processes of H2O2/UV and O3 has been studied. When the decolorization rate of Acid Yellow 61 in both reactions presented similar, it was found there are some differences from the results of AOX removal and production of inorganic ions and organic acids. The results reveal that the H2O2/UV has beneficial effect on mineralization than O3 only for degradation of Acid Yellow 61 solution and it is possible for enhancement of method efficiency by taking longer reaction time and addition of high concentration of oxidants.
