采用电化学方法研究了3种氨基酸化合物对铜的缓蚀作用。它们抑制阴极电流密度，并使腐蚀电位向更负的值移动。通过反射红外光谱证实了氨基酸与铜表面的相互作用。量子化学参数由PM3半经验计算得到。谷氨酸具有较小的氮原子净正电荷和较多的氧原子净负电荷。谷氨酸的缓蚀作用的改善是由于其结构中的氧原子稳定了其在铜表面上的吸附。
The corrosion inhibition of three amino acid compounds on copper was investigated by electrochemical method. They suppressed cathodic current densities and shifted the corrosion potential towards more negative values. The interaction between amino acid and copper surface was certified by reflected FT-infrared spectroscopy. The quantum chemical parameters were obtained by PM3 semi-empirical calculation. Glutamic acid has the smaller net positive charge of nitrogen atom and the more net negative charge of oxygen atoms. The improved inhibition of glutamic acid was due to the stabilization of its adsorption on the copper surface by the oxygen atoms in its structure.
