The feasibility and efficiency of the hydrogen peroxide produced by an electrolysis cell reactor was investigated. From regulating voltages for the given reaction time, the concentration of the hydrogen peroxide was gradually increased with increasing voltages.
Optimal voltage range was found to be 10～15 V. The concentration of hydrogen peroxide was much higher with oxygen gas than without oxygen gas in the cathodic chamber. But there was a little difference in the generating rate of hydrogen peroxide regardless of the presence of nitrogen gas.
Under given conditions, the maximum value of ICE(Instantaneous Current Efficiency) was about 38%, and then current density was 74 mA/cm2. The specific energy consumption was 0.694[㎾h/kg-H2O2]. Since Esp (Specific Energy Consumption)was very little value, It did not demand high energy in this system.
Using the hydrogen peroxide gained in the experiment, Fenton's reaction was conducted and the removal of nitrobenzene, 3-chlorophenol and dye wastewater was studied. This results were very similar to the Fenton's reaction by using commercial hydrogen peroxide.
