| 摘 要： | 本文用电化学方法将同多钼酸催化剂固定在导电聚吡咯膜微电极上,从而制得了具有表面功能的同多钼酸掺杂的聚吡咯(IPMo/PPy)膜修饰微电极。该电极不仅保持了同多钼酸的电化学活性和电催化性能,而且在硫酸水溶液中进行电位扫描时具有良好的稳定性。在酸性水溶液中固定在PPy膜内的IPMo能催化还原ClO_3~-和BrO_3~-,并且对BrO_3~-的催化效应比对ClO_3~-的更强。

| Abstract: | In this paper,the isopolymolybdic acid catalyzer was fixed on the conductive polypyrrole film mi-croelectrode by electrochemical mathod,thus the isopolymobdic anions doped polypyrrole (IPMo/PPy) film modified microelectrodes with surface function have been prepared- This modified microelectrode not only maintains the electrochemical and electrocatalytic properties of isopolymolybdic acid,but also has good stability upon potential cycling in sulfuric acid solution. The IPMo in PPy film can catalyze the reduction of ClO-3 and BrO-3 in acidic aqueous solution and the catalytic effect on BrO-3 is larger that on ClO-3. |
