CURRENT/POTENTIAL OSCILLATIONS INDUCED BY ADSORPTION AND DESORPTION OF INHIBITOR IN Fe/HCI MEDIUM
Fe／HCl体系中缓蚀剂吸脱附诱导的电流／电位振荡

Electrochemical oscillations in HCl 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 studied.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 H 2SO 4 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.
