The reaction characteristics and mechanism were analyzed by UV analysis, liquid chromatography, double reciprocal mapping and other analytical methods. The experimental results showed that the degradation efficiency of phenol of Fenton reaction is improved with the addition of Mn (salen)2 complex. It maintained a certain degradation ability under different pH systems or excess H2O2. Due to the high valence manganese intermediate,which is converted from the manganese ion in the complex, the oxidation of organic matter and the degradation efficiency have been accelerated.The activation energy of the degradation reaction was reduced by 35.9% after adding the complex into the fenton system. The catalytic activity of [Mn(salen)]2 remained 60% after 7 times repeat uses. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书修改说明 -->
