Sažetak
Corrosion inhibition of aluminium in 1 M HCl solution using 30% (v/v) ethanol solution of Lavandula angustifolia L. oil was studied by potentiodynamic polarization and EIS methods. It was found that lavender oil effectively inhibits aluminium corrosion in concentration range from 50 to 500 ppm by volume. Polarization curves showed that lavender oil behaves as cathodic inhibitor for aluminium in HCl solution. EIS results confirmed that active compounds present in this oil have ability to form protective layer on aluminium surface. Inhibitive effect was probably caused by adsorption of active compounds such as linalool, linalyl acetate, 1, 8-cineole and camphor on aluminium surface. This study showed that ethanol solution of Lavandula angustifolia L. oil could be used as an effective green corrosion inhibitor for aluminium corrosion in acidic medium, but must be handled as mixture of inhibitors which can act synergistically to inhibit aluminium corrosion.
