摘    要:用电聚合法在铂微盘电极上制备了聚吡咯膜,并将其在电解质水溶液中进行了过氧化处理。所得到的过氧化膜是非电子导体而为离子导体,膜具有多孔笥的特征。该膜具有排有离子的作用,而对大阳离子如多巴胺具有高度的选择性。

关 键 词:微电极 过氧化 聚吡咯膜 化学修饰电极 多巴胺

Abstract:Polypyrrole (PPy) film was electropolymerized on platinum disk microelectrode and treated by overoxidation in aqueous electrolyte solution. The film produced is electroni- cally non-conductive but ionically conductive and possesses porosity. This film has highly cation-selective properties such as for dopamine and can reject many interferences of aaions. The influencing factors of the film on the selective response of dopamine were also discussed..
Keywords:Microelectrode   overoxidized polypyrrole film   chemically modified electrod   dopamine
