摘要

含氮类缓蚀剂分子中的N 既能与碳钢发生吸附作用形成保护膜，又能破坏细菌细胞膜，从而杀死细菌。为了探究苯并咪唑餐饮废油衍生物缓蚀剂对Q235 碳钢的缓蚀性能，将苯并咪唑餐饮废油衍生物2-十七烷基-5-甲基-1H-苯并[d]咪唑缓蚀剂添加到模拟海水中，采用失重法、电化学测试以及扫描电镜进行表征；利用分子动力学模拟探究缓蚀剂分子在Fe 表面的吸附性能参数。结果表明:苯并咪唑餐饮废油衍生物缓蚀剂添加量为500 mg/L 时，缓蚀率可达91.95%，分子动力学模拟结果表明苯并咪唑餐饮废油衍生物缓蚀剂在铁表面为平面吸附构型。

Abstract

The N in the nitrogen-containing corrosion inhibitor molecules can not only adsorb with carbon steel to form a protective film， but also destroy the bacterial cell membrane and thereby killing the bacteria. In order to explore the corrosion inhibition performance of benzimidazole catering waste oil derivative corrosion inhibitor on Q235 carbon steel， benzimidazole catering waste oil derivative 2-heptadecyl-5-methyl-1H-benzo[d]imidazole corrosion inhibitor was added into simulated seawater， and the weight loss method， electrochemical test and scanning electron microscope were used to characterize the corrosion. Meanwhile， molecular dynamics simulation was employed to investigate the adsorption performance parameters of corrosion inhibitor molecules on the Fe surface. Results showed that when the added amount of benzimidazole catering waste oil derivative corrosion inhibitor was 500 mg/L， the corrosion inhibition rate could reach 91.95%. The molecular dynamics simulation results revealed that the corrosion inhibitor molecules had a planar adsorption configuration on the Fe surface.
