摘要：

Gemini imidazoline surfactant was synthesized from the lauric acid and triethylenetetramine. The inhibitive effects of Gemini imidazoline surfactants on copper in hydrochloric acid solution were studied by electrochemical polarization and impedance spectroscopy. It was found that the inhibitive efficiency depended on the structure of surfactants inhibitive, concentrations of surfactants inhibitive, solution concentration effect were investigated. The results show that Gemini imidazoline surfactant has excellent inhibitive effect on copper in hydrochloric acid solution, and the inhibitive efficiency of Gemini imidazoline in hydrochloric acid solution is better than traditional monomer imidazoline surfactant. The higher the concentration of Gemini imidazoline surfactant, the better the inhibitive effect is.The lower the concentration of acid solution, the higher the inhibitive efficiency is.
