研究了HCl介质中活性电位区有机缓蚀剂在Fe电极表面吸脱附诱导产生的电化学振荡现象，及缓蚀剂浓度、电极电位和溶液搅拌等因素对振荡行为的影响。结果表明，在HCl介质中Fe电极的活性电位区同样得到了规整的电流振荡波，但相同条件下的振荡行为要弱于H2SO4介质中，随缓蚀剂浓度升高，振荡波的周期变长，振荡 减弱；由阴极到阳极，电流振荡波形不同，周期也有所增长，搅拌对电流振荡无明显影响，同时报道了该缓蚀体系中恒电流电位振荡的新现象。
Electrochemical oscillations in HCI medium induced by the adsorption and desorption of the organic inhibitor on a rotating iron electrode in the active potential region of iron are observed and investigated. The effects of the inhibitor concentration, potential and stirring on the oscillation are stud- ied. The results show that in the HCl medium the regular current oscillation waves are measured in the active potential region of iron electrode too, however the oscillations are feebler than those in the H2S04 medium;The higher the concentration of the organic inhibitor, the longer the period is and the feebler the oscillations is; With the increase of the potential from cathode to anode, the oscillation waveform is changed and the period becomes longer; Furthermore, the stirring doesn't influence the electrochemical oscillation obviously. At the same time, a new potential oscillation is observed in the system. KEY
