| 摘 要： | 通过在玻碳电极(GCE)表面电化学沉积金(Au)微粒和聚苯胺(PAni)制备了Au微粒和聚苯胺修饰的玻碳电极(Au/PAni/GCE),并通过循环伏安法研究了亚硝酸根在该修饰电极上的电化学行为,以及探讨了修饰电极对亚硝酸根电催化氧化性能的影响因素。结果表明:Au/PAni/GCE对亚硝酸根具有良好的电催化氧化作用,该性能受聚苯胺和Au微粒的负载量以及底液pH值的影响。

| Abstract: | Au particles and polyaniline modified glass carbon electrode （Au/PAni/GCE） was prepared by electrochemically deposite. The electrochemical behaviors of nitrite on Au/PAni/GCE were studied with cyclic voltammetry and the influencing factors of elecrocatalytic oxidation of nitrite on Au/PAni/GCE were discussed. The result show that Au/PAni/GCE has favorable elecrocatalytic oxidation of nitrite and the elecrocatalytic oxidation of nitrite is affected by the amount of polyaniline and Au particles and the pH of base solution. |
