摘要
采用电化学法和失重法研究了榅桲提取物(QE)在1mol / l盐酸中对低碳钢的腐蚀和电化学性能的抑制作用。利用傅里叶变换红外光谱和紫外光谱分析了木瓜中含有的具有重要缓蚀作用的化合物(如氨基酸和类黄酮)。极化试验和电化学阻抗谱结果表明，在200 ~ 1200ppm范围内增加提取物的浓度可提高其抑菌效果。在浓度为1200 ppm时，极化和EIS的抑制率最高，分别为95%和93.0%。在此基础上，我们认为木瓜提取物是一种混合型缓蚀剂。用扫描电镜和原子力显微镜观察了1 M HCl浸泡钢试样的表面，结果表明，在不含200-1200 ppm缓蚀剂的情况下，榅桲提取物具有有效的防腐蚀作用。图形抽象
Corrosion and Electrochemical Characterization of St37 in the Presence of Quince Extract as a Green and Sustainable Inhibitor
The inhibitory performance of quince extract (QE) on the corrosion and electrochemical properties of low-carbon steel in 1 molar hydrochloric acid was studied by electrochemical methods and weight loss measurement. The chemical compounds contained in quince that offer substantial corrosion inhibition impacts (e.g., amino acids and flavonoids) were examined by Fourier-transform infrared spectroscopy and ultraviolet. Polarization tests and electrochemical impedance spectroscopy results showed that increasing the concentration of the extract in the range of 200–1200 ppm increased its inhibition efficiency. The highest inhibition efficiency of the extract based on polarization and EIS results was respectively 95% and 93.0%, both observed at a concentration of 1200 ppm. Based on the results, quince extract was considered as a mixed-type corrosion inhibitor. Scanning electron microscopy and atomic force microscopy of the surface of steel specimens immersed in 1 M HCl without and with 200–1200 ppm of the inhibitor showed the effectiveness of quince extract in preventing corrosion.
期刊介绍：
Electrocatalysis is cross-disciplinary in nature, and attracts the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. Electrocatalysis provides the unique international forum solely dedicated to the exchange of novel ideas in electrocatalysis for academic, government, and industrial researchers. Quick publication of new results, concepts, and inventions made involving Electrocatalysis stimulates scientific discoveries and breakthroughs, promotes the scientific and engineering concepts that are critical to the development of novel electrochemical technologies.
Electrocatalysis publishes original submissions in the form of letters, research papers, review articles, book reviews, and educational papers. Letters are preliminary reports that communicate new and important findings. Regular research papers are complete reports of new results, and their analysis and discussion. Review articles critically and constructively examine development in areas of electrocatalysis that are of broad interest and importance. Educational papers discuss important concepts whose understanding is vital to advances in theoretical and experimental aspects of electrochemical reactions.
