Sažetak
Among numerous compounds that have been tested and applied industrially as corrosion inhibitors, those that are non-toxic are now far more strategic than in the recent past. Furthermore, these green corrosion inhibitors except non-toxicity must have good inhibition efficiency. The exploration of natural products of plant origin as inexpensive green corrosion inhibitors is an essential field of study, because they possess molecules with electron-rich atoms, multiple bonds or aromatic rings which can act as adsorption centres. One of the well-known and frequently used aromatic herbs in Mediterranean region is basil (Ocimum basilicum L.). Essential oils isolated from O. basilicum L., can be classified in four major basil essential oil chemotypes: methyl chavicol-rich, linalool-rich, methyleugenol-rich, methyl cinnamate-rich, and numerous subtypes. The aim of this work is to investigate the essential oil of basil (Ocimum basilicum L., chemotype linalool) and its main component, linalool as green inhibitors of the aluminium corrosion in acidic medium. The study was done by gravimetric measurements on different temperature range. Considering that inhibition efficiency of the plant extract vary with concentration, temperature, period of immersion and pH of corrosive medium, adsorption behavior of investigated compounds was obtained, and some thermodynamic and kinetic parameters were calculated, too.
