Аннотация
The corrosion inhibition of carbon steel in CO2-saturated 3% NaCl solution by anise extract (AE) dissolved in ethylene glycol (EG) was studied using weight loss, electrochemical and surface analysis (AFM) techniques. Inhibition efficiency increased with increase in AE concentration and temperature, reaching maximum value of 93% at 400 ppm AE concentration. Polarization results show that AE functions as a mixed-type inhibitor. Corrosion inhibition is assumed to occur by physicochemical adsorption following Langmuir adsorption isotherm model. Morphological studies of the carbon steel electrode surface undertaken by AFM confirm the adsorption of the extract on the metal surface.
