Abstract
In this study, graphite, Fe wires, Ti-Fe bimetal wires and Ag-Fe bimetal wires were selected as cathodes. Azo dye methyl orange was used as model pollutant. The results indicate that the decay rate of methyl orange was the highest in the case of Ag-Fe bimetal wires as expected and the obtained decay rate was 99.22% at 5V cell voltage in the presence of 0.25 mM Fe2+, 14 mM Na2SO4, pH 3 for 60 minutes electrolysis. The kinetics of electro-Fenton process for methyl orange decoloration reaction should be regarded as first-order reaction by the experimental facts in this study.
