It is based on the weight loss (WL) analysis, kinetic and thermodynamic parameters, and electrochemical methods both stationary (Potentiodynamic polarization (PDP)) and transient (Electrochemical impedance spectroscopy (EIS)). The inhibition efficiency of inhibitors increases for the concentration of 1.5 g/L; reaching a high value of 93.11 and 87.88 % in 1 M HCl solution at 308 K for OE and DE, respectively. The thermodynamic kinetic parameters showed that the adsorption of OE and DE on the MS surface follows the Langmuir adsorption isotherm. Furthermore, PDP measurements exhibited that the studied of each inhibitor performs as a mixed-type inhibitor. OE shows itself to be the best aqueous extract of Aaronsohnia pubescens aerial parts to prevent against the corrosion of mild steel.
