| 摘 要： | 采用Fenton试剂氧化降解亚甲基蓝，通过对亚甲基蓝染料处理过程中的紫外、红外光谱分析可知，Fenton对亚甲基蓝的结构造成了严重破坏，探讨了Fenton试剂氧化降解亚甲基蓝的反应动力学．结果表明，Fenton氧化过程中，H2O2初始浓度、FeSO4初始浓度及温度对反应都有影响，且确定反应为一级反应，其动力学方程式为：-dC／dt=0．1842exp（-3．53／RT）·H2O2]始^0.88561·Fe^2＋]始^0.88519.

| Abstract: | According to the UV-Vis spectrum,it is concluded that Fenton oxidation is an effective method for the degration of Methlene Blue.According to the IR spectrum,it is concluded that structure of Methylene Blue was destroyed by Fenton reagent.The degradation process of Methylene Blue in Fenton reaction was investigated.The kinetics of the degradation of Methylene Blue by Fenton oxidation was studied.It is shown that the temperature and the initial concentration of hydrogen peroxide and ferrous sulphate affect t... |
