Study on Light Degradation of 2,4-dichlorophenol in Wastewater by Using Excimer UV Source

摘要：

A study on degradation of 2,4-dichlorophenol in aqueous solution using 172nm excimer UV source is reported. Degradation products were analyzed by Gas chromatography time-of-flight mass spectrometry. The experiment results show that a low concentration (1mg/L) and a high concentration (10mg/L) of 2,4-dichlorophenol are directly irradiated separately. By GC-TOFMS technique analysis, the results indicate that under the irradiation the 1mg/L of 2,4-dichlorophenol is extremely unstable and decompose completely in 1.5 minutes. However, after 10 minutes irradiation on the 10 mg/L of 2,4-dichlorophenol, the degradation products of 2-chlorophenol, phenol, benzenediol and benzoquinone are detected. The possible process of the degradation of 2,4-dichlorophenol by excimer UV resource is presented.
