| 中文摘要 |
| 研究了成对电氧化技术降解酸性红B染料废水过程.通过高效液相色谱(HPLC)对阴阳极室降解过程中的产物进行了检测,结合UV-Vis变化曲线及TOC、CODCr变化过程,发现阳极室脱色比较快,生成多种中间物质;阴极室中间产物很少且降解更完全.电解140min时阴极室中TOC和CODCr去除率分别达到71.70%和56.40%,而阳极室中去除率分别为25.15%和27.57%.实验结果表明,阴阳极室中生成氧化物质的氧化能力不同而使酸性红B在阴阳极室按不同的机理降解. |
| 英文摘要 |
| The electrochemical degradation of acid red B (ARB) with hydrogen peroxide and hypochlorite ion electroge-nerated by paired electrooxidation technology was investigated. High performance liquid chromatography (HPLC) was used to inspect the degradation process of ARB. Through analyzing chromatographic survey and UV-Vis spectra, as well as the removal of CODCr, TOC and color in the anode and cathode cells, the degradation processes of ARB in different cells were different. The color removal in the cathode cell was slower than in the anode cell, but the CODCr and TOC removal, which were 71.70% and 56.40% respectively, was higher than the removal in the anode cell, which were 25.15% and 27.57%. It maybe result from the different oxidation capabilities of the electrogenerated substances in the anode and cathode cells. |
