چکیده مقاله:

The aim of this research was to remove COD and color from a hazardous municipal landfill leachateusing electro-Fenton process. The effects of four important parameters including H2O2/Fe2+ molarratio, current density, pH and reaction time on the process were carefully considered. The responsesurface methodology (RSM) was applied to minimize the number of runs and investigate the optimumoperating conditions. Thirty runs were carried out and the optimum conditions for COD and colorremoval were statistically obtained as 95.80 and 96.36% at H2O2/Fe2+ molar ratio 0.23, current density79.20 mA, pH 4.61 and reaction time 14.72 min.
