| 摘 要： | 核桃叶提取物是一种"绿色"缓蚀剂.本文采用失重法、动电位极化曲线研究了核桃叶提取物在0.5mol/LH2SO4溶液中对冷轧钢的缓蚀作用.结果表明:核桃叶提取物对冷轧钢具有较好的缓蚀作用,在冷轧钢表面的吸附符合校正的Langmuir吸附等温式,极化曲线表明,核桃叶提取物为混合型缓蚀剂.

| Abstract: | Juglans leaves extract was investigated as a green inhibitor.The inhibition effect of the plant extract on the corrosion of cold rolled steel(CRS) in 0.5 mol/L H2SO4 was studied by weight loss and potentiodynamic polarization curves methods.The results show that the extract is a good inhibitor in sulfuric acid for CRS,and the adsorption of the plant inhibitor on the CRS surface obeys the amended Langmuir adsorption isotherm equation.Polarization curves show that the pant extract is a mixed-type inhibitor. |
