Abstract: The comparison of degradation of Acid Yellow 61 as a model dye
compound in both oxidation processes of H_2O_2/UV and O_3 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 H_2O_2/UV has beneficial effect on mineralization than O_3 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.
