| 中文摘要: |
| 采用吸附、焙烧法制备了活性炭-纳米二氧化钛催化剂,对偶氮染料甲基橙溶液进行了电催化氧化降解规律的研究.实验结果表明, 纳米二氧化钛催化剂的催化效果显著,该工艺能有效的去除废水中的有机物,去除机制主要是电致H2O2、·OH对有机物的氧化、降解.以水杨酸为探针性物质,推测出电催化氧化过程中羟基自由基·OH的产生. |
| 英文摘要: |
| The activator, nanometer titanium dioxide-loaded active carbon was prepared by adsorption-roasting method. A novel electric catalysis system was introduced to treat methyl orange solution, the typical azo dyes. The experiment results indicated that the electrochemical oxidation process could efficiently remove and degrade organic pollutants. The removal efficiency could be attributed to the oxidation of electrogenerated H2O2, hydroxyl radicals generated in electro-Fenton process. Furthermore, salicylic acid had been used as a probe to discuss the generation of the hydroxyl radical. |
