The desalination plants wieldy used CuNi alloys. However, it faces a fundamental corrosion problem in a 3.5% NaCl solution containing sulfide ions. In this research, we have examined ionic liquid's corrosion and bacterial inhibition activity, i.e., 1-Dodecyl-3-methylimidazolium iodide (IMD-IL). The obtained data from weight loss and electrochemical reveals the corrosion inhibitive performance of IMD-IL is 96.8% at 100 mg/L. The EIS suggests increasing the charge transfer resistance and film resistance with increasing IMD-IL amount, supporting the inhibitive action of IMD-IL molecules. The biological activity results reveal the deactivation of SRB action after the addition of IMD-IL molecules. The SEM and EDX studies support the IMD-IL adsorption onto the CuNi surface. The molecular docking results confirmed that IMD-IL could bind the cytochrome c, inhibiting its activity and thereby interrupting the electron transport pathway between bacteria and the CuNi.

咪唑基离子液体减轻海水淡化厂的腐蚀和细菌生长：实验、表面和分子对接分析


海水淡化厂广泛使用铜镍合金。然而，它在含有硫离子的3.5% NaCl溶液中面临着根本性的腐蚀问题。在这项研究中，我们检测了离子液体的腐蚀和细菌抑制活性，即1-十二烷基-3-甲基碘化咪唑鎓（IMD-IL）。失重和电化学数据表明，IMD-IL 在 100 mg/L 浓度下的缓蚀性能为 96.8%。 EIS表明随着IMD-IL用量的增加，电荷转移电阻和薄膜电阻增加，支持IMD-IL分子的抑制作用。生物活性结果表明添加IMD-IL分子后SRB作用失活。 SEM 和 EDX 研究支持 IMD-IL 在 CuNi 表面上的吸附。分子对接结果证实IMD-IL可以结合细胞色素c，抑制其活性，从而中断细菌与CuNi之间的电子传递途径。
