摘要
报道了在玻碳电极上共价键合二茂铁的新型化学修饰电极。研究了该电极对丙二醛的电催化作用。以微分脉冲伏安法测定丙二醛，方法具有较好的灵敏度和选择性。丙二醛的峰电流与其浓度在２０×１０－６～２０×１０－３ｍｏｌ／Ｌ呈良好的线性关系。
A new ferrocene_modified glassy carbon electrode is described. With this electrode, the electrocatalysis of malonaldehyde(MA)was studied. Malonaldehyde can be determined with this ferrocene_modified electrode by differential pulse voltammetry. The method is sensitive and selective. A good linear relationship exists between the peak current and MA concentration in the range from 2 0×10 -6 to 2 0×10 -3 mol·L -1 .
