本文用旋转圆盘电极、稳态极化曲线、交流阻抗及恒电流充电曲线等方法研究了Zn在常温(30℃)和低温(-20℃)的KOH水溶液中阳极溶解和钝化过程的规律。从而提出其反应机理,并用最优化程序在TRS-80微型计算机上计算了反应机理中基元反应的速度和动力学参数的最佳值。由动力学参数计算的φ～i关系定量地符合从阳极溶解至钝化前整条极化曲线实验数据。旋转圆盘电极的转速效应、交流阻抗值以及恒电流充电电量值也都与提出的反应机理相符合。
In this paper, the regularity of anodic dissolution and passivation of Zn in aqueous KOH solution at normal temperature (30 ℃) and low temperature (-20 ℃) was studied by rotating disc electrode, steady state polarization curve, alternating current impedance and galvanostatic charge curve. . The reaction mechanism was put forward and the best value of the velocity and kinetic parameters of the elementary reaction in the reaction mechanism was calculated by the optimization program on the TRS-80 microcomputer. The φ ~ i relationships calculated from the kinetic parameters quantitatively fit the experimental data from the anodic dissolution to the entire polarization curve before passivation. Rotating disk electrode speed effect, AC impedance value and the value of the constant charge current are also consistent with the proposed reaction mechanism.
