Abstract

Essential oil of a medicinal plant (Salvia officinalis), used as an eco-friendly inhibitor for the corrosion of carbon steel in 1 M HCl, is presented. The corrosion inhibition properties of Salvia officinalis essential oil were evaluated by gravimetric and electrochemical methods. The results showed that the inhibition efficiency increases with the increase in inhibitor content to reach 82.84 at % 1.8 g/L. X-ray Photoelectron Spectroscopy (XPS) analyses showed that the corrosion inhibition effect is linked to the adsorption of Salvia officinalis essential oil molecules on the steel surface. It was shown that the adsorption of the investigated inhibitor on the substrate surface obeyed to Temkin isotherm model.

鼠尾草精油作为盐酸溶液中碳钢的新型环保抑制剂：重量减轻，电化学和XPS研究

摘要

介绍了一种药用植物（Salvia officinalis）的精油，它是一种环保型缓蚀剂，可在1 M HCl中腐蚀碳钢。用重量法和电化学法评价了丹参挥发油的缓蚀性能。结果表明，随着抑制剂含量的增加，抑制效率也随之提高，在％1.8 g / L时达到82.84。X射线光电子能谱（XPS）分析表明，缓蚀作用与丹参挥发油分子在钢表面的吸附有关。结果表明，所研究的抑制剂在底物表面的吸附符合Temkin等温模型。
