Degradation of 2,4-dichlorophenol (2,4-DCP) in aqueous by glow discharge electrolysis (GDE) has been investigated. Ultraviolet (UV) absorption spectra, atomic force microscopy (AFM), high performance liquid chromatography (HPLC) and gas chromatogram-mass spectrum (GC/MS) are used to monitor the degradation process and to identify the major oxidation intermediate products. It has been found that 2,4-DCP undergoes a series of intermediate step, which leads to form a number of intermediate products, mainly isomeric chlorophenols and aliphatic acids. These products are further oxidized, eventually, mineralized into CO(2) and Cl(-). A degradation pathway for 2,4-DCP is proposed on the basis of detection of intermediate compounds.
研究了辉光放电电解（GDE）对水中2,4-二氯苯酚（2,4-DCP）的降解情况。采用紫外（UV）吸收光谱、原子力显微镜（AFM）、高效液相色谱（HPLC）和气相色谱-质谱联用（GC/MS）来监测降解过程并鉴定主要的氧化中间产物。结果发现，2,4-DCP经历了一系列中间步骤，生成了许多中间产物，主要是异构氯酚和脂肪酸。这些产物进一步被氧化，最终矿化为CO₂和Cl⁻。基于中间化合物的检测结果，提出了2,4-DCP的降解途径。
