研究了聚甲基红膜修饰电极 ( PMRE)的制备方法及其在水溶液中的电化学行为 ,用循环伏安技术对该膜的电化学特性进行了初步的探讨 ,结果表明 PMRE对抗坏血酸具有很好的电催化作用 ,催化峰电流与底物浓度在较宽的范围内有良好的线性关系 ,可用于实际样品分析
The preparation method of polymethyl red film modified electrode (PMRE) and its electrochemical behavior in aqueous solution were studied. The electrochemical characteristics of PMRE were studied by cyclic voltammetry. The results showed that PMRE had a good effect on ascorbic acid Good electrocatalysis, catalytic peak current and substrate concentration in a wide range of good linear relationship can be used for actual sample analysis
