【摘要】 于铂电极上修饰一层Ｎ（３二茂铁乙酰胺基）丙基吡咯聚合物膜，应用循环伏安法对聚合物的电化学性能进行研究，发现Ｎ位取代吡咯聚合物的电活性大大降低；聚合物中的二茂铁基团氧化还原性能稳定，制成酶电极后，在＋０．２Ｖ对葡萄糖有一明显的催化峰，而对抗坏血酸、尿酸则几乎没有响应．该葡萄糖电极性能稳定，连续工作十天，响应值基本不变更多还原

【Abstract】 A poly [N (3 ferrocene acetamino propyl pyrrole)]film modified electrode was fabricated and studied by cyclic voltammetric method. The result shows that the modified electrode can give stable redox peaks of ferrocene, and an obvious catalytic peak due to glucose; This modified electrode was used to tabricate a glucose sensor which operates at +0.2 V, so that the ascorbic acid or uric acid doesn’t affect the accuracy detection of glucose concentration. The sensor has a linear range of 0.1～10 mmol/L glucose, which the period of long term stability and response time of the sensor are about ten days and 2 min.更多还原
