摘　　要：通过电聚合溴酚蓝于玻碳电极上制备了聚溴酚蓝修饰玻碳电极。电化学方法研究了聚溴酚蓝修饰玻碳电极的电化学性质。考察了两种异构体p-硝基苯酚与m-硝基苯酚在聚溴酚蓝修饰玻碳电极上的电化学表现,结果表明聚溴酚蓝修饰玻碳电极对p-硝基苯酚与m-硝基苯酚的还原表现出优异的电催化性能和选择性能。依此发展了一种运用聚溴酚蓝修饰玻碳电极同时伏安测定p-硝基苯酚与m-硝基苯酚的方法。考察了影响测定的因素并对实际样品进行分析,获得了较满意的结果。Poly bromophenol blue modified glassy carbon electrode was prepared by electropolymerization of bromophenol blue on glassy carbon electrodes. The properties of poly bromophenol blue modified glassy carbon electrode were studied with electrochemical method. The electro performance of p-nitrophenol and m-nitrophenol in poly bromophenol blue modified glassy carbon electrode were studied and the results show that the poly bromophenol blue modified glassy carbon electrode shows excellent electro-catalytic properties and select properties on the p-nitrophenol and m-nitrophenol reduction. So the use of poly bromophenol blue modified glassy carbon electrode for Simultaneous voltammetric determination of p-nitrophenol and m-nitrophenol method was proposed. Factors affecting the determination were studied. The real samples were analyzed and satisfactory results were obtained.
