| 摘 要： | 采用电催化氧化技术（Elcctrocatalysis Technology）降解酚类化合物，以紫外-可见光谱和反相高效液相色谱研究了苯酚降解的机理，利用有机分子结构的理论及循环伏安曲线对不同酚类化合物降解的差并进行了分析，实验发现本体系对多羟基酚类化合物具有很好的降解效果，5种酚被氧化降解的趋势依次是：邻苯二酚〉间苯三酚〉对苯二酚〉间苯二酚〉苯酚，邻苯二酚的CODCr去除率可达到95％以上。

| Abstract: | A novel electro-catalysis oxidation method for hydroxybenzene wastewater degradation, including Phenol, Catechol, Hydroquinone, Resorcinol and Phloroglucinol, was described. The mechanism of phenol degradation was proposed by UV-Vis spectra and HPLC. The results indicated that phenol was decomposed into small molecule compounds and inorganic molecule, such as H_2O and CO_2. The organic molecule structure theory and I-V cyclic voltammograms were used to discuss the orderliness of hydroxybenzene degradation. The experiments showed that the technology was availability for pretreatment of phenol wastewater. The COD_(Cr) removing rate for catechol was about 95%. |
