Four imidazolium‐based ionic liquids (ILs) were selected to investigate the inhibiting effect of ILs with various alkyl chain lengths on the corrosion of mild steel in H2S and HCl solution using electrochemical experiments, weight loss and surface analyses, and quantum chemical study. The results demonstrated that these ILs acted as mixed‐type inhibitors and efficiently inhibited the corrosion of mild steel in H2S and HCl solution. Their excellent corrosion inhibition ability was due to their adsorption process on the metal surface, which followed the Langmuir adsorption isotherm. Furthermore, extending the alkyl chain length in the ILs could improve their inhibition performance.

离子液体对H2S和HCl溶液中低碳钢腐蚀的抑制作用
通过电化学实验，重量损失和表面分析以及量子化学研究，选择了四种咪唑基离子液体（IL）来研究不同烷基链长的ILs对H 2 S和HCl溶液中低碳钢腐蚀的抑制作用。。结果表明，这些离子液体可作为混合型抑制剂，并有效抑制H 2 S和HCl溶液中低碳钢的腐蚀。它们出色的腐蚀抑制能力是由于它们在金属表面上的吸附过程遵循了Langmuir吸附等温线。此外，延长IL中的烷基链长度可以改善其抑制性能。
