采用电化学极化法（Tafel外推法和极化电阻法）和失重法研究了无毒咪唑衍生物在氯化钠溶液中作为铜缓蚀剂的效果。研究结果表明，分子量较大的缓蚀剂，尤其是含苯环的缓蚀剂，具有较好的缓蚀性能。由Freundlich等温式计算的吸附自由能表明，所研究的咪唑衍生物在铜表面上是物理吸附的。(C)2002爱思唯尔科技有限公司。保留所有权利。
The efficiency of nontoxic imidazole derivatives as copper corrosion inhibitors in sodium chloride solutions was studied by electrochemical polarization methods (Tafel extrapolation and polarization resistance method) and weight-loss measurements. Results obtained during this study show that inhibitors with higher molecular weight, especially those with a phenyl ring, have better inhibiting properties. The values of free energy of adsorption, as calculated from Freundlich isotherm, indicate that investigated imidazole derivatives physisorbe on the copper surface. (C) 2002 Elsevier Science Ltd.
