摘　　要：用循环伏安法(CV)将茜素红S修饰于玻碳电极表面,成功地制备出对硝基酚具有良好电催化作用的聚茜素红薄膜修饰电极(PARSE)。在差分脉冲伏安图(DPV)上,邻硝基苯酚、2,4-二硝基苯酚、2,2,4-三硝基苯酚分别出现一、二、三个还原峰。根据DPV图,研究了不同硝基酚在PARSE上的还原反应,并推断了反应机理。利用这一特性,可以进行不同硝基酚的定性与定量分析。Alizarin red S was modifided in surface of glassy carbon electrode, and a Poly（Alizarin Red S） film modified electrode（PARSE） which had a good electrocatalysis for the nitrophenol were prepared successfully by cyclic voltammetry（CV）. In the differential pulse voltammetry grams（DPV）, the o-nitrnphenol, 2,4-dinitrophenol and 2,4,6-trinitropbenol were observed respectively to have one, two and three sensitive deoxidize peaks. According to DPV curves, the reductive reaction mechanism of different nitrophenols in PARSE was studied. Using this characteristic, it can be set up that qualitative analysis and quantitative analysis methods.
