Electrochemical Impedance Spectroscopy (EIS) has been known as a powerful tool for analyzing electrode reaction mechanism. In this review the history of EIS, the definition of electrochemical impedance, the general concept of transfer function, and the measurement method of electrochemical impedance using a transfer function analyzer are first introduced. Then, analytical methods of impedance spectra using electrical equivalent circuits and the kinetic theory of electrochemical reactions are stated. Finally, the future scope of EIS is briefly given.

Anodic polarization curves of electro-polished Type 304 stainless steel were measured in organic acid solutions of eight types to develop a safe and environmentally friendly passivation treatment. The pitting potentials of the steel passivated in the solutions were examined in a deaerated 3.5%NaCl solution. Among the organic acid solutions, 8%DL-malic acid, 8%citric acid, 8%L-tartaric acid and 8%glucono-δ-lactone were found to be suitable as treatment solutions because of the low current densities(<0.02 A・m-2)of the passive state and high pitting potentials(>700 mV vs. Ag/AgCl(sat. KCl))of the passive films. Passive films formed on Type 304 stainless steel by natural immersion into 8%DL-malic acid+0.98%H2O2, 8%citric acid+0.98%H2O2, 8%L-tartaric acid+0.98%H2O2 and 8%glucono-δ-lactone+0.98%H2O2 showed high pitting potentials(>1000 mV)in NaCl solutions of 3.5% - saturation concentration. For solutions containing H2O2, the pitting-potentialraising effects were greater on an electro-polished surface than on a buffer(#400)-polished surface.
