A Kinetic Equation for Various Electrochemical Techniques at a Finite Disk Electrode

本文提出了一个适用于有限圆盘电极上多种电化学技术的一般表达式。在可逆情况下，用该方程数值计算得到的电流值与Ｋ．Ａｏｋｉ报道的结果相符合，在所有时域内，误差小于０．５％。在不可逆情况下，把该表达式用于诸如线性扫描伏安法、阶梯和方波伏安法等具体技术的详细描述将在下文报道。

A general expression for various electrochemical techniques at a finite disk electrode is presented. It is given by:Where:and r. denoted the radius of the electrode. The currents numerically calculated by eqn. (1) are in good agreement with the results reported by K. Aoki in all regions of time within 5‰ errors in the case of a reversible reaction. The particularization of this general solution to specific techniques such as linear; scan voltammetry, staircase and square wave voltammetry in the case of an irreversible reaction, will be reported in subsequent papers.
