Over the past decade, the corrosion inhibition of organic ligands has been extensively studied in numerous experiments in acid media. The number of published papers related to corrosion inhibition studies of organic ligands has been rising exponentially. The organic ligands have high inhibitive properties due to their capability to adsorb on the surface of metal by forming a protective layer. Having lone pair electrons (S, N, O) and multiple bonds (π bonds) allow them to adsorb on the surface of metals efficiently. However, there is very limited and less comprehensive information on the characterization of corrosion inhibition performance of organic ligands on the surface of metals. Therefore, this review paper provides a comprehensive review on the corrosion inhibition performance through various characterization methods, which are the electrochemical method [Electrochemical Impedance Spectroscopy (EIS), Polarization], Scanning Electron Microscope (SEM) with Energy Dispersive X-ray (EDX), and Langmuir Isotherm, which are thoroughly discussed herein. © 2022, Malaysian Society of Analytical Sciences.
