摘要：

To the wastewater of dye stuff, a satisfactory effect of degradation can hardly be achieved by traditional physical, chemical, or biological degradation treatments. The recently developed electrochemical degradation, however, has advantages such as high energy efficiency, wide scope of application, environmental compatibility. It has been used in the degradation treatment of wastewater of dye stuff, whereas the relative research on the mechanism and the process has scarcely been done. Therefore, we choose methyl orange (MO), a typical type of azo dyes, as the subject investigated. Chemometric methods are adopted to analyze the UV-visible absorption spectrum in the process of degradation and to study the mechanism.
