Abstract

Salix leaves water extract was studied for the corrosion inhibition of mild steel in H₂SO₄ at different temperatures. Energy dispersive spectroscopy (EDX), Gas Chromatography Mass spectrometry (GC–MS), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used in our investigation. By applying different techniques as potentiodynamic polarization and electrochemical impedance to detect the effect of the Salix active ingredients onto the mild steel in acidic medium, it was confirmed that the corrosion process was inhibited. Salix water extract acts by decreasing the available cathodic and anodic reaction area. The adsorption isotherm has revealed that the inhibitor adsorbed on the metal surface obeys Langmuir and Temkin isotherm.

硫酸中低碳钢的新型绿色缓蚀剂

摘要

研究了柳叶提取物在不同温度下对H ₂ SO ₄中低碳钢的腐蚀抑制作用。在我们的研究中使用了能量色散光谱（EDX），气相色谱质谱（GC-MS），傅里叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）。通过应用电位动力学极化和电化学阻抗等不同技术来检测Salix活性成分在酸性介质中对低碳钢的影响，证实了腐蚀过程得到了抑制。柳树水提取物通过减少可用的阴极和阳极反应面积而起作用。吸附等温线表明吸附在金属表面的抑制剂符合Langmuir和Temkin等温线。
