Date Palm Seed Extract for Mild Steel Corrosion Prevention in HCl Medium

The inhibition effects of the date palm seed extract corrosion mild steel in 0.5 M HCl at different concentrations are investigated by potentiodynamic polarisation (PDP), electrochemical impedance spectroscopy (EIS) and weight loss tests. Additionally, this study provides a fundamental understanding aromatic adsorption on iron (Fe) surfaces. Furthermore, surface morphology extracts performed using scanning electron microscopy (SEM) Fourier transform infrared (FTIR). maximum efficiency 95, 96, 91% were realised 1400 mg/L for PDP, EIS, loss, respectively. inhibitive action DPS against an acid solution has been supported SEM analysis. FTIR showed that contained hydroxyl (−OH) methoxyl (−OCH3) functional groups. DFT depicted sites oxygen (O) carbon (C) atoms as deduced from Fukui functions, Mulliken atomic charge, highest occupied molecular orbital-lowest orbital (HOMO-LUMO) preferred to form chemical bonds donating electrons Fe surface. coordinate between O C metal resulted high value. In conclusion, is effective inhibitor protect acidic medium.
