摘要
采用失重法、动电位极化法和EIS法研究了虎茎对0.5 M H2SO4溶液中低碳钢的缓蚀作用。结果表明，该提取物在0.5 M H2SO4溶液中具有良好的抑制作用。抑制效果随萃取物浓度的增加而增加。提出了植物提取物中成分在金属表面的吸附抑制行为。
OXYSTELMA ESCULENTUM Stem Extracts as Corrosion Inhibitor for Mild Steel in Acid Medium
The corrosion inhibitive action of oxystelma esculentum stem on mild steel corrosion in 0.5 M H2SO4 solution was studied using weight loss method, potentiodynamic polarization and EIS measurements. The results obtained indicate that the extracts functioned as good inhibitors in 0.5 M H2SO4 solution. Inhibition efficiency was found to increase with extract concentration. The adsorption of constituents in the plant extract on the surface of the metal is proposed for the inhibition behavior.
