| 摘 要： | 为了提高Fenton试剂处理有机污染物的效率,探索最佳处理条件,以亚甲基蓝-苯酚混合溶液为模型污水,进行了Fenton试剂氧化亚甲基蓝退色反应的影响因素实验.对不同试验条件下褪色反应动力学过程进行了在线跟踪、拟合和比较研究发现,苯酚和亚甲基蓝在反应体系中存在竞争.苯酚会影响Fenton试剂对亚甲基蓝的退色反应效率;退色反应分3个阶段,本研究得到了第1阶段和第3阶段的反应速率常数的表达式. |

| Abstract: | The decolorization of methylene blue using Fenton reagent was conducted with the on - line time monitoring of reaction process. The effects of phenol on the deeolorization rate were observed. The experimental results suggested that the process of the Fenton oxidation could be divided into three regions according to the kinetic characteristics. Then, the two kinetic models of three regions were developed. |
| Keywords: | Fenton decolorization kinetics |
