1 实验原理与方法1 1 实验原理电子自旋共振 (ＥＳＲ)技术是检测自由基的最直接有效的手段 ,·ＯＨ自由基与ＤＭＰＯ(二甲基呲咯啶 )生成ＤＭＰＯ -ＯＨ ,可直接用ＥＳＲ检测。本实验即采用Ｆｅｔｏｎ反应 -产生·ＯＨ自由基的基本反应 :Ｈ2 Ｏ2 +Ｆｅ2 +Ｆｅ3+·ＯＨ + Ｏ
1 Experimental Principles and Methods 1 1 Experimental Principles Electron Spin Resonance (ESR) technology is the most direct and effective means of detecting free radicals. OH radicals and DMPO (Dimethyl Carboxyridine) generate DMPO -OH and can be used directly. ESR testing. In this experiment, the Feton reaction was used and the basic reaction of producing OH radicals was: H2O2 + Fe2 + Fe3 + · OH + O
