| 摘 要： | 研究了旋转圆盘铜阳极在酸性NaCl溶液中恒电位电流振荡现象。用logI—E曲线初步研究产生电流振荡的电位范围。实验证实 ,恒电位电流振荡的振幅随转速的增加而减小 ,诱导期随转速的增大而增加 ,转速对振荡频率的影响不大 ;振荡与H+浓度有很大关系 ,振幅随H+浓度降低而减少 ,当H+浓度为 0 0 5mol/dm3 时 ,没有出现电流振荡现象

| Abstract: | The currrent oscillatory phenomena of Cu anode in various acidic sodium chloride solutions were studied with potentiostatic rotating disk electrodes. The potential range of oscillations has been established by log I-E curve. The oscillatory amplitude of current at fixed potentials decreased as rotation rate increased and the induction period elongated. However, the rotation rate almost has no effct on oscillatory freguensy. The oscillation was greatly influenced by H concentration: the amplitude reduced at lower H concentrtion and the oscillatory phenomena were not observed at 005 mol/L |
