摘要
以电化学方法制备·OH ,并探讨了体系内的反应机理 ;电生成·OH对十二烷基苯磺酸钠 (dodecylben zenesul phonicacid (6 ) sodiumsalt ,DBS)水溶液有明显的降解效果 ,CODCr降解率 >85 % ;比较了处理前后DBS的红外光谱、UV、I V循环伏安曲线的变化。·OH可以将DBS中的烷基碳链断裂 ,并最终将其降解为H2 O和CO2 等无机小分子。
The electrochemistry process to produce Fenton reagents was described. The in situ oxidation of dodecylben-zenesulphonic acid-(6)-sodium salt (DBS) with electrogenerated hydroxyl radicals was investigated. The I-V cyclic voltammograms was measured. The IR spectrogram result indicated that DBS was decomposed into small molecule compounds and inorganic molecule, such as H 2O and CO 2. So far, the degradation of the DBS was confirmed by the UV spectrogram and the chemical analysis. The COD Cr removal rate was high than 85%.
