摘要: 本文提出了受扩散控制的it与tβ的关系式以及计算β值的正确表达式,讨论了同时受扩散和电极反应速率控制的极谱电流与时间的关系,利用所得的理论公式可方便地求得标准电极反应速率常数(ks),理论结论与实验相符。

关键词: 电流时间曲线方程, 可逆和不可逆过程, 反应速率常数

Abstract: The equations of i-t curves on single drops for reversible and irreversible processes are described. The experimental results obtained in literatures are in good agreement with the theoretical conclusions . The standard heterogeneous rate constant (ks) values are calculated from the theoretical e-quation by using the experimentally determined values of β'.
