用谱学方法研究铜在Fe（CN）_6^（3－）溶液中的腐蚀行为

Spectroscopic Investigations of the Corrosion and Forming Film of Copper in Fe(CN)Solution

用ＦＴ－ＩＲ、ＵＶ－Ｖｉｓ和ＸＰＳ等分子光谱和电子能谱方法研究了铜在Ｆｅ（ＣＮ）溶液中的腐蚀过程，表面膜的形成及其改性。结果表明，腐蚀膜主要由（ＣＮ）６（大量）和（ＣＮ）６（少量）组成，并夹杂有Ｋ４Ｆｅ（ＣＮ）６和Ｋ３Ｆｅ（ＣＮ）６．

FT-IR、UV-Vis and XPS spectroscopic methods were used for studying the corrosion processes、film formation and improvement of copper in Fe(CN)solution. The resultsshown that the corrosion film is essentially composed of CuFe(CN)6and a little Cu(CN)6,K4Pe(CN)6 and K3Pe(CN)6 are also found in the film,especially in its surface layer.
