Abstract

Abstract: 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. Graphical Abstract: ga1 Highlights: Ionic liquid as a corrosion and bacterial growth inhibitor for CuNi. The CuNi surface screened for the IMD-IL adsorption via SEM and EDX. The biological activity results support SRB deactivation with addition of IMD-IL. The molecular docking results confirmed the IMD-IL protection ability.
