Purpose

This paper aims to reduce environment pollution caused by benzotriazole. The authors chose one of the best inhibitors from 2-aminobenzimidazole, 2-methylbenzimidazol, 2-mercaptobenzimidazole and benzimidazole in combination with benzotriazole.

Design/methodology/approach

The electrochemical measurement indicated that 2-methylbenzimidazol had the best inhibition behavior. Then, it was mixed with benzotriazole. Techniques such as field emission scanning electron microscopy, atomic force microscopy, Raman spectroscopy and optical contact angle measurements were used.

Findings

The results showed that the inhibition efficiency was up to 99.98%, when the mixture concentration was 20 mmol/L and the molar ratio 1:1.

Originality/value

1-benzotriazole was mixed with 2-methylbenzimidazol for the first time. During the exist of methyl, 2-methylbenzimidazol has the better inhibition; this point was ignored by researchers.

四种苯并咪唑衍生物和苯并三唑在铜表面的腐蚀抑制行为

目的

本文旨在减少苯并三唑对环境的污染。作者从2-氨基苯并咪唑，2-甲基苯并咪唑，2-巯基苯并咪唑和苯并咪唑与苯并三唑的组合中选择了最佳的抑制剂之一。

设计/方法/方法

电化学测量表明2-甲基苯并咪唑具有最佳的抑制行为。然后，将其与苯并三唑混合。使用了诸如场发射扫描电子显微镜，原子力显微镜，拉曼光谱和光学接触角测量等技术。

发现

结果表明，当混合物浓度为20 mmol / L，摩尔比为1：1时，抑菌率可达99.98％。

创意/价值

第一次将1-苯并三唑与2-甲基苯并咪唑混合。在甲基存在期间，2-甲基苯并咪唑具有更好的抑制作用；这一点被研究人员所忽略。
