| 摘 要： | 研究了聚邻苯二酚／铂复合膜（Pt／polymer／GC）修饰电极对甲醛的催化氧化作用。结果表明，甲醛在Pt／polymer／GC电极上的氧化过程是一表面控制过程。电解质体系对甲醛的催化氧化有明显影响：在0．5mol／L硫酸中，甲醛主要发生第一步氧化生成甲酸的反应。甲醛的第一氧化峰电流随浓度的增加而增大，并且呈线性关系，可用于甲醛的检测。

| Abstract: | The catalytic activity for the formaldehyde oxidation was investigated on the polycatechol/platinum composites modified electrode.The results indicated that the electrochemical oxidation of formaldehyde on the composites modified electrode was a diffusion-controlled process,which was influenced predominantly by the electrolyte.The main reaction occurred in 0.5 mol/L H2SO4 solution was the oxidation of formaldehyde to methyl acid,and the first oxidation peak current was linearly related to the formaldehyde c... |
