The corrosion and corrosion inhibition of CK10 carbon steel in CO2-saturated 3% NaCl solution by anise
extract (AE) dissolved in ethylene glycol (EG) was studied using polarization curves, electrochemical impedance
spectroscopy (EIS) and surface analysis (AFM) methods. Inhibition efficiency increased with increase in AE
concentration and temperature. The data suggest that AE functioned as inhibitor via a mixed-inhibitor mechanism and
the inhibition process is attributed to the formation of a chemically adsorbed film of AE and EG on the surface of the
metal via its polycentric adsorption sites. Thermodynamic adsorption parameters of studied inhibitor were calculated
using the Langmuir adsorption Isotherm. Morphological studies of the carbon steel electrode surface were undertaken
by atomic force microscopy (AFM).
