采用电化学方法考察了3%NaCl溶液中2-正十一烷基咪唑对Cu 的缓蚀作用.结果表明烷基咪唑对Cu电极的阴、阳极电化学过程均有明显的抑制作用.随着 烷基咪唑浓度的增加，分子聚集体的形成，导致烷基咪唑在电极表面吸附程度的降低，其缓 蚀能力有所下降.
The inhibiting efficiency of 2-n-undecylimidazole(U DIM)for copper in 3%NaCl solution was investigated by electrochemical impedance s pectroscopy technique and potentiostatic polarization method.The results show th at UDIM suppress both cathodic and anodic corrosion reaction of copper.A remarka ble decrease in the protective effects of UDIM was observed because of the aggre gate formed by UDIM with the increasing of concentration.A new absorption with λmax=214 nm,which attribute to the adsorption of UDIM aggregates,was detected by UV-Visible Spectroscopy.
