In the study the response variables of Y-1 and Y-2 were selected as COD removal rate (%) and color removal rate(%), and efficacy variables of A, B, anc C were selected as H2O2 concentration (mmol/L), reaction time (h) and H2O2/Fe2+. The experimental design was used as a two-level factorial design. In the corner points 2(3) = 8, in the center points 3 and a total of 3.(8+3)=33 experiments were conducted. Effect of H2O2 concentration (mmol/L), reaction time (h) and H2O2/Fe2+ molar ratio on COD removal rate and color removal rate were investigated. The optimum conditions for maximum COD removal rate and color removal rate were at H2O2 concentration 8 mmol/L, reaction time 3 h and H2O2/Fe2+ molar ratio 2.6. At optimum conditions 82% COD removal rate and 93% color removal rate were achieved.tr10.5505/pajes.2014.37928info:eu-repo/semantics/openAccessFentonResponse surface methodologyOptimizationArticle216239247N/AWOS:000443157200004
