12-钼磷杂多酸(PMo_(12))聚/N,N-二甲基苯胺修饰电极的制备及电化学研究

Preparation and electrochemical study of phosphomolybdic acid(PMo_(12))-polymerized N,N-dimethylaniline film modified electrode

采用恒电位电解法在水溶液中成功地制备了 1 2 -钼磷杂多酸 (PMo1 2 ) 聚N ,N -二甲基苯胺 (PD MA)薄膜修饰电极 ,并研究了其电化学性质 .此膜在酸性溶液中具有良好的氧化还原性能 ,且制备方法简单、快速 ,为有机

Poly(N,N-dimethylaniline)(PDMA)was prepared by electrochemical polymerization of the corresponding monomer and 1∶12-phosphomolybdic acid was modified on the PDMA film electrode through electro- adsorption. This modified electrode maintains the electrocatalyic properties of heteropolymolybdic acid and has good stability and catalytic activity on the reduction of bromate ion and iodate ion in acidic aqueous solution.
