The photochemical decolorization of two dyes, namely Acid Yellow 54 and Basic Blue 9, was studied using the UV/H2O2 and UV/Fenton processes. The effects of the amount of H2O2 and FeSO4 as well as the initial pH solution on decolorization kinetics of both the dyes were investigated. The pseudo-first order kinetic model was applied to predict the decolorization of the selected dyes at the different operational conditions and results showed that this model fitted very well with the experimental data. The obtained results also showed the efficiency of UV/Fenton process to quickly degrade aqueous effluents polluted by Acid Yellow 54 and Basic Blue 9 compared to the UV/H2O2 process.
