研究了中性红在玻碳电极表面电聚合成膜的方法和条件，对膜内电荷传输过程和电化学特性分别用循环伏安技术和电位阶跃暂态技术进行了初步探讨。该膜对维生素Ｃ和亚硝酸盐有较强的电催化作用，催化电流与底物浓度在很宽的范围内呈线性关系，可用于实际样品的分析。
The method and conditions for the electropolymerization of neutral red on the surface of glassy carbon electrode were studied. Cyclic voltammetry and potential step transient technique were used to investigate the charge transport and electrochemical properties in the film respectively. The membrane of vitamin C and nitrite have a strong electrocatalytic effect of catalytic current and substrate concentration in a wide range of linear relationship can be used for the actual sample analysis.
