Electro-Fenton process with activated carbon fiber as the cathode and Ti/SnO2
as the anode was used in the treatment of acetophenone wastewater. Effects of Fe2+
concentration and electric current density on acetophenone degradation were investigated. It was indicated that the phenyl in acetophenone molecular could be destroyed by electro-Fenton process and chemical oxygen demand (CODCr
) of the wastewater decreased significantly. Compared with traditional two-dimensional electrode process in which no Fe2+
was added, the pollutant removal efficiency and current efficiency by electro-Fenton process were both higher. Current density has significant influences on the pollutant removal. Higher current density raised pollutant removal efficiency while lowering current efficiency. Under the conditions of electric current density 10.0 mA/cm2
0.1 mmol/L and initial pH 4.0, the removal efficiencies of CODCr
and acetophenone at 180 min were 58.96% and above 90%, respectively.
