Degradation of 4-Chlorophenol in Aqueous Solution by High-voltage Pulsed Discharge-Ozone Technology
|
Abstract:
The combination of high voltage pulse discharge and ozonation as an advanced oxidation technology was used to investigat the degradation of 4-chlorophenol (4-CP) in water. The factors that affect the rate of degradation were discussed. The 1.95×10-3 mol/L solutions of 4-CP were almost completely (96%) degraded after the discharge treatment of 30min. The degradation of 4-CP was investigated as a function of the ozone concentration, radical scavenger and electrode distance. The rate of 4-CP degradation increases with an increase in ozone concentration and a decrease in the electrode distance from 20mm to 10mm. The presence of radical scavenger decreased the rate of 4-CP degradation.
