چکیده انگلیسی
Our model of diffuse double layer with the addendum of the effect of hydrophobic forces fits well the adsorption data of Fluorescein on iron oxides at different pH in the studied range. At lower pH electrostatic forces by ligand-exchange are predominant. In the range of pH 9-11 hydrophobic forces are managing the Fluorescein adsorption on the iron oxides, with the formation of outer-sphere complexes through van der Waals/hydrophobic forces. It is interesting that in the three iron oxides studied, the adsorbed amount in this range is similar.
