摘要：

Impedance measurements were performed on iron in sulphate and chloride media with varying additions of chloride and sulphate respectively. These experiments were performed within pH 0-4 and current density up to 0.2 A cm-2. The impedance diagrams showed a gradual transition from the iron-chloride to iron-sulphate systems. These results were interpreted on the basis of the previously proposed iron dissolution mechanism. © 1990.
