采用失重法、电化学阻抗谱（EIS）、Tafel极化和原子力显微镜（AFM）等技术研究了香蕉皮水提液对碳钢在1M HCl溶液中的缓蚀作用和吸附效果，以及香蕉皮随成熟度的变化。提取物的抑制能力随成熟度的增加而降低。此外，浸提物的特征在于FTIR光谱，紫外可见光谱和高效液相色谱（HPLC）技术。研究了各萃取物的吸附行为，结果表明，各萃取物的吸附机理均符合Langmuir等温吸附模型。(C)2014爱思唯尔有限公司版权所有。
The inhibition and adsorption effects of the aqueous extracts of Musa paradisica (Banana) peels on mild steel corrosion in 1 M HCl as well as change in inhibition efficiency with ripening of the peels are investigated by weight loss measurement, electrochemical impedance spectroscopy (EIS), Tafel polarization and atomic force microscopy (AFM) techniques. Inhibition ability of the extracts decreases with the maturity stages. Furthermore, the extracts are characterized by FTIR spectroscopy, UV-visible spectroscopy and high performance liquid chromatography (HPLC) techniques. Adsorption behavior of the extracts is also studied, which suggest Langmuir isotherm model as a most suitable adsorption mechanism. (C) 2014 Elsevier Ltd. All rights reserved.
