摘要

采用电化学技术研究了管道钢在硫酸环境中，在没有和有商品芦丁(CR)的情况下的电化学腐蚀行为。极化和阻抗曲线表明，芦丁具有良好的缓蚀特性，其缓蚀特性受阴极控制较大。温度稍微升高，CR的缓蚀能力有所提高。CR能够将电荷转移电阻提高4天，并且在研究环境中显示出更光滑的腐蚀表面形态。腐蚀表面膜分析表明，芦丁在管道钢表面有化学吸附。

Corrosion Inhibition and Electrochemical Behaviour of Commercial Rutin in an Acidic Environment

The electrochemical corrosion behaviour of pipeline steel in a sulphuric acid environment, in the absence and presence of commercial Rutin (CR), was studied using electrochemical techniques. The polarization and impedance curves showed an excellent corrosion inhibition characteristic of Rutin, which was more cathodically controlled. Temperature increase slightly improved CR corrosion inhibition capacity. CR was able to increase the charge transfer resistance up to four days, and showed a smoother corrosion surface morphology in the study environment. Analysis of the corrosion surface film showed that Rutin was chemically adsorbed onto the pipeline steel surface.

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.
