| 摘 要： | 基于纳米材料的优异特性,根据文献采用一步液相反应法,制备了六边形纳米CuⅠ.并将其制成碳糊电极,采用经典的三电极系统:CuⅠ修饰的碳糊电极为工作电极,饱和KCl的Ag/AgCl电极为参比电极,铂片为对电极,在不同浓度的Cd2+溶液中,用电化学交流阻抗方法研究了其对Cd2+的电化学行为,实验结果表明电荷传递电阻Ret随着Cd2+浓度的增加而减小,实现了CuⅠ对Cd2+的电化学传感.该分析方法操作简单易行,具有潜在的应用价值,而且这些研究结果拓展了纳米材料修饰电极在电分析化学中的重要意义.

| Abstract: | Based on the excellent properties of nanomaterial,we use hexagonal CuⅠ powder to modify a carbon paste electrode,in order to investigate the electrochemical behavior in the presence of Cd2+and realize the detection of Cd2+with CuⅠ modified electrode.What is worth mentioning is that this method is simple and easy to operate,which makes it have potential applications.Additionally,these results show that the expansion of nanostructure electrodes is of great importance in electroanalytical chemistry. |
