| 摘 要： | 通过循环伏安法、旋转圆盘电极等方法研究了有机锡化合物在铂电极上的电化学行为，以及吸附有机锡化合物的铂电校对硝酸根和亚硝酸根的催化还原性能和pH的影响。结果表明二乙基锡在铂电极上的吸附对N03^-和N02^-的还原具有催化作用。还原时过电位减少，根据其还原过程的电化学行为，提出了可能的催化机理。同时通过催化过程动力学分析由实验得到了催化速率常数。

| Abstract: | The electrochemical characteristics of organotin on the platinum electrode were studied by cyclic voltammetry, rotating disk electrode and other methods. The catalytic behavior of the platinum adsorbed with organotin was also studied. The results show that Et2SnCl2 can catalyze the reduction of nitrate and nitrite. The over potential for the reduction of nitrate and nitrite on the modified electrode is dropped obviously. The catalytic kinetics of the electrode was also studied. |
