Description
Résumé:Biojarosite as a replacement for commercial iron catalyst in the oxidative degradation of the dye Rhodamine B was confirmed and established. Investigations on the oxidative degradation by Fenton's oxidation and UV-Fenton's oxidation with EDTA at neutral pH were conducted and degradation of target compound was evaluated. UV-Fenton's oxidation was shown to be efficient over Fenton's oxidation in the degradation of Rhodamine B with removal efficiency of 90.0%. Design of Experiments was performed with Box-Behnken design. Investigation was conducted for the predicted values separately for both Fenton's oxidation and UV-Fenton's oxidation and the Rhodamine B removal was taken as response. Variable parameters biojarosite, H2O2 dosage and EDTA were optimized in the range of 0.1-1 g/L, 2.94-29.4 mM and 10-100 mM, respectively. A quadratic regression model is fitted for both Fenton's and UV-Fenton's oxidation. Analysis of variance (ANOVA) is performed and model fit is discussed
