![عکس صفحه اول مقاله: Fluconazole as an inhibitor for aluminium corrosion in 0.1 M HCl Fluconazole as an inhibitor for aluminium corrosion in 0.1 M HCl](/preview/png/596441.png)
The interfacial behavior of fluconazole (FLC) between aluminium and hydrochloric acid has been investigated by using weight loss technique at 30–50 °C. The results showed that fluconazole is an excellent corrosion inhibitor for aluminium in acidic medium. Inhibition efficiency increased with increase in the concentrations of fluconazole but decreased with rise in temperature. The adsorption of the inhibitor on the aluminium surface is found to accord with Temkin adsorption isotherm. Some thermodynamic and activation parameters have been calculated and analysed. The mechanism of physical adsorption is proposed from the values of Ea and ΔGads° obtained. The correlation of inhibition effect and molecular structure of fluconazole was then discussed by quantum chemistry study to further provide insight into the mechanism of the inhibitory action.
