摘要
本文采用快速三角波和稳态极化等方法研究了乌洛托品在铜电极上的吸附及其对溶解过程的影响，结果表明：电极界面电容与电位间符合Ｍｏｔｔ－Ｓｃｈｏｔｔｓｃｈ关系式，乌洛托品在铜电极界面上吸附，标准吸附自由能△Ｇ＝－１１．６ｋＪ·ｍｏｌ（－１），随着乌洛托品浓度加大，平衡电极电位和平带电位正移，该吸附对阳极的阻化作用较阴极大．
The fast triangular wave and controlled potential techniques were used to study the adsorption of urotopin on copper electrode and its influence on copper anodic dissolution. The results show that capacitance (C(sc)) and potential follows Mott-schottky's equation and the standard free energy (△G) of the absorption of urotopin on copper electrode is-11. kJ·mol(-1).With the increase of urotopin concentration, the equilibrium potential and the flat band potential of copper electrode become positive. The adsorption prohibited the anodic dissolution of copper.
