Inhibitive Action of Anethum graveolens L. oil on Aluminium Corrosion in Acidic Media

Jasna Halambek Katarina Berkovic

Abstrak

The inhibition effect of Anethum graveolens L. essential oil on the corrosion of aluminium in 1 M hydrochloric acid solution was investigated by weight loss, potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS) methods. Inhibition efficiency increased with increasing oil concentration, but decreased with temperature. The adsorption of Anethum graveolens L. essential oil obeys Langmuir adsorption isotherm. Polarization curves show that Anethum graveolens L. essential oil in acidic medium behaves as cathodic inhibitor. The Nyquist plots showed that on increasing the inhibitor concentration, the charge transfer resistance increased, confirming the adsorption process mechanism. Values of inhibition efficiency obtained from weight loss and electrochemical measurements are in good agreement.
