Abstract
In this study, decolorization of Reaktoset Brilliant Orange P-2R and Telon Turquoise M-GGL dyes in aqueous solution was investigated under Fenton (H2O2/Fe2+) and photo-Fenton (H2O2/Fe2+/UV) oxidation reactions. At first, batch experiments were carried out to determine the effects of ferric ion and hydrogen peroxide concentrations, as well as pH and mixing speed on the reaction rate to find optimum conditions. The experiments denoted that the decolorization efficiencies of Fenton and photo-Fenton processes were very close to each other for both dyes. During the second stage, the experimental data were analyzed by using the zero, first and second-order and Behnajady-Modirshahla-Ghanbery (BMG) kinetic models. BMG model provided the best correlation of the data. It was concluded that efficient color removals of Reaktoset Brilliant Orange P-2R and Telon Turquoise M-GGL dyes could be obtained when optimum conditions of Fenton and photo-Fenton oxidation processes were performed. In addition, the results could provide fundamental knowledge for the real industrial operators to effectively treat as mentioned dyes.
