| 摘 要： | 制备了GC/MWNTs/PMo12O340-修饰电极,研究了其在硫酸溶液中的电化学行为,采用循环伏安法研究了修饰电极对抗坏血酸的电催化特性。结果表明,该修饰电极在硫酸溶液中的电化学行为是表面控制过程。抗坏血酸的浓度在3×10-3～1×10-2mol/L范围内,催化电流与抗坏血酸的浓度呈现良好的线性关系,该修饰电极具有较好的稳定性。

| Abstract: | GC/MWNTs/PMo_ 12 O 3-_ 40 modified electrode was prepared and its electrochemical behavior in H_2SO_4 solution was studied.The electrochemical characteristics of the modified electrode were studied by using cyclic voltammetry.The result showed that electrochemical behavior of the modified electrode in H_2SO_4 solution was a diffusion-controlled process.There was a good linear relationship between the peak current and the concentration of ascorbic acid in the range of 3×10-3 ～1×10-2 mol/L.The modified electrode had good stability. |
