采用失重法、动电位极化曲线和电化学阻抗谱（EIS）研究了荔枝皮提取物在0.5 M H2SO 4溶液中对碳钢的缓蚀作用。结果表明，荔枝皮提取物具有混合型缓蚀作用。结果表明，该萃取液对金属的缓蚀作用是由于其在金属表面的吸附作用，其吸附符合Langmuir吸附等温式。紫外-可见光谱、傅里叶变换红外光谱和扫描电子显微镜的研究证实，缓蚀剂分子对碳钢的缓蚀作用是通过吸附实现的。
The corrosion inhibition of mild steel in 0.5 M H2SO4solution by the extract of litchi peel (Litchi chinensis) was studied by weight loss method, potentiodynamics polarization and electrochemical impedance spectroscopy (EIS). The results show that the litchi peels extract acts as mixed-type inhibitor. The inhibition of corrosion is found to be due to adsorption of the extract on metal surface, which is in conformity with Langmuir’s adsorption isotherm. UV–Vis, Fourier transform infrared (FT-IR) spectroscopy and Scanning electron microscopy (SEM) studies confirm that the inhibition of corrosion of mild steel occurs through adsorption of the inhibitor molecules.
