Abstract
The adsorption of fluconazole (FLU) on aluminum surface from 0.1 M HCl solution was studied using chemical technique at 30°-50° C. The values for free energy of adsorption, ΔG°ads, were calculated at each surface coverage, h, of the studied compound by applying the mathematical model of the Bockris-Swinkels adsorption isotherm. The phenomenon of physical adsorption is proposed from the value of Gibbs free energy, ΔG°ads, obtained from the Bockris-Swinkels adsorption equation and the mean adsorption energy, E, using the adsorption isotherm model of Dubinin-Radushkevich (D-R). A zero-order kinetics relationship with respect to aluminum was obtained with and without FLU from the kinetic treatment of the data.
