Through taken the measurements of pH, TOC, UV-Vis spectra and high-performance liquid chromatograph in the degrading process of solution ,it was found that the COD of dye solution increased, pH continuing declined and TOC reduced gradually. The UV-Vis spectra and high-performance shown that though dye molecules had been destroyed, Strong Chromophore Azo Double Bond of dye was certainly under attack, the big conjugated system was vandalized and dye molecules were decolorized degradation, but they were not completely changed into carbon dioxide and other inorganic matter by mineralization, it appeared accumulation of aromatic ring and double benzene nucleus, so it is thus evident that complete destruction of aromatic ring is more difficult than the double benzene.

通过测定直接大红染料脱色过程中的溶液pH、TOC、紫外可见光谱图和高效液相色谱图可知，在脱色处理时间(6h)范围内，染料溶液的COD值增大， pH值持续下降，TOC值逐渐降低，结合紫外可见光谱图和高效液相色谱图，说明染料分子虽然已经遭到破坏，染料分子内强生色基团偶氮双键确实遭到攻击，大的共轭体系被破坏，染料分子被脱色，却没有完全被彻底矿化成二氧化碳等无机物，出现了芳环和萘环结构的累积现象，可见完全破坏芳环比破坏偶氮双键发色团更困难。
