摘要：

The films formed on the surface of copper during its anodic dissolution in the neutral or acidic sulfate solution were studied with the in-line digital holography. The results showed that the mixture films were formed on the surface of copper in the neutral or acidic sulfate solution: the inner oxide film and the outer salt film. Although there are defects in the oxide film caused by the sulfate ions, the oxide film other than the salt film mainly inhibits the anodic dissolution at the high anodic potentials.
