摘要：

This study focused on the degradation and toxicity change of 4-chlorophenol (4-CP) in aqueous solution by contact glow discharge electrolysis (CGDE) with and without Fe2+. It was found that the addition of Fe2+ increased the degradation rate of 4-CP and decreased the toxicity of the solution. After 90 min CGDE treatment, only 28.0% 4-CP was removed and EC50 increased from 33.8 to 63.1 mg/L. With 25.0 mg/L Fe2+ in solution, the degradation rate of 4-CP reached 93.3% and EC50 changed from 35.9 to 93.9 mg/L after 90 min CGDE treatment.
