摘要

本文合成了一种基于钴-菲罗啉-对羟基苯甲酸三元复合物的新型缓蚀剂。通过失重测量、电化学测试、表面分析和量子化学计算，研究了其在 0.5 M HCl 溶液中对碳钢的防腐效果。结果表明，Co-phen-phba 三元复合物在 298 K 和 328 K 条件下的抗腐蚀效率分别为 97% 和 86%。Co-phen-phba 三元复合物的优异防腐性能可能归功于无机和有机缓蚀剂的结合。理论计算确定了结构与缓蚀剂防腐效果之间的相关性。

Synthesis, characterization and anticorrosion performance of a new corrosion inhibitor based on cobalt- phenanthroline- p-hydroxybenzoic acid ternary complex

In this paper, a new corrosion inhibitor based on cobalt- phenanthroline- p-hydroxybenzoic acid ternary complex was synthesized. Its anti-corrosion effects on carbon steel in 0.5 M HCl were investigated by weight-loss measurements, electrochemical tests, surface analyses, and quantum chemical calculations. The results indicated that the Co-phen-phba ternary complex exhibits excellent anti-corrosion efficiencies of ∼97 % at 298 K and ∼86 % at 328 K. The excellent anti-corrosion performance of Co-phen-phba ternary complex could be attributed to the combination of inorganic and organic corrosion inhibitors. Theoretical calculations established the correlation between the structure and the anti-corrosion effect of corrosion inhibitor.
