Abstract

Natural oil extracted from apricot seeds was evaluated as carbon steel corrosion inhibitor in 1 M hydrochloric acid, using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and weight loss measurements. The measurements show that apricot seed oil is a good inhibitor for carbon steel corrosion in a hydrochloric environment, and this inhibitive action was mainly due to its adsorption onto the carbon steel surface, and active sites blocking. The above results showed that apricot seed oil acted as a mixed-type corrosion inhibitor, and that its adsorption onto the carbon steel surface obeyed the Langmuir adsorption isotherm. The inhibition effectiveness increased with the inhibitor concentration, and reached 83.49% at 0.5 g/L, in a 1 M HCl medium. Some thermodynamic parameters of the studied inhibitor were calculated and discussed.

杏杏仁油作为绿色缓蚀剂在盐酸介质中对钢的腐蚀作用

采用动电位极化、电化学阻抗谱(EIS)和失重测量等方法，对杏籽天然油在1 M盐酸中作为碳钢缓蚀剂进行了评价。结果表明，杏籽油在盐酸环境下对碳钢具有良好的缓蚀作用，其缓蚀作用主要是由于杏籽油在碳钢表面的吸附和活性位点的阻断作用。上述结果表明，杏籽油作为混合型缓蚀剂，其在碳钢表面的吸附服从Langmuir吸附等温线。随着缓蚀剂浓度的增加，缓蚀剂的缓蚀效果逐渐增强，在1 M HCl介质中，当浓度为0.5 g/L时，缓蚀效果达到83.49%。对所研究缓蚀剂的热力学参数进行了计算和讨论。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
