ABSTRACT
The aim of this study is to investigate the corrosion inhibition efficiency of expired Linezolid (LIN) on mild steel (MS) in 1 M HCl at 303 K using experimental techniques such as electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), and Scanning Electron Microscopy (SEM). Results show that the LIN is a good inhibitor and inhibition efficiency (IE %) reach 90.2% for EIS and 93.2% for PDP at an optimum concentration of 2.5 mM. EIS measurements revealed a charge transfer-controlled corrosion mechanism and the formation of a thick double layer on the steel surface. Polarization curves show that the addition of inhibitors to the corrosive media dramatically changed the anodic Tafel constants (βa) and cathodic Tafel constants (βc), indicating a mixed type nature. Scanning electron microscopy analyses affirmed the formation of a protective film on mild steel surfaces.
