自从极谱催化波问世以来,在这廿余年中愈来愈受到人们的重视,因为它只用了简单的方法和仪器,但是却大大地提高了分析的灵敏度,应用的实例也越来愈多,有关的理论也同时得到了发展。但是,在过去的工作中,对於极谱催化电流的性质研究得比较多,而对於极谱催化波(电流-电位的关系)研究得比较少,Kern对受扩散和化学反应(平行反应,下同)的极谱催化波的性质在理论上只作了简单的论述,並未作实验验证,在其他人的工作中也还没有看到精确测量这一类催化波的半波电位来验证Kern的理论。关於受电极反应和化学反应同时控制的极谱催化波的性质,虽然Brdicka和Koutccky的论文涉及这个问题,但缺乏明确的结论,也没有实验验证。本文从理论上推导了受扩散、电极反应和化学反应同时控制的极谱波方程式,並分别各种情况进行了讨论,对於受扩散和化学反应控制以及受电极反应和化学反应控制的极谱波方程式作了实验验证,实验结果与理论值相符。

The theoretical relationship of the current-potential for the electrode processes controlled by both diffusion and charge transfer rates and simultaneously proceeded and followed by a first-order chemical reactions is developed.
