| Résumé : |
A series of Schiff bases with hydroxyl anchoring group/s in various positions were synthesised. Their visible light absorption and electrochemical and physicochemical adsorption properties were investigated. Results show that the studied compounds have adequate highest-occupied-molecular-orbital and lowest-unoccupied-molecular-orbital levels that match with the conduction band of titanium dioxide and the redox potential of the electrolyte. Adsorption of azomethine compounds with hydroxyl group/s on titanium dioxide was studied. Experimental data show that the introduction of two ?-hydroxyethyl groups can greatly enhance the adsorption efficiency of the studied Schiff base on titanium dioxide. Sorption kinetics was measured for di-(?-hydroxyethyl)aminobenzyliden-2-aminobenzothiazol. Results show rapid initial sorption (<30 min), followed by a slower rate of increasing uptake between 0.5 and 6 h. Kinetic data were modelled using pseudo-first-order, pseudo-second-order, and intraparticle diffusion kinetics equations. These results indicate that the pseudo-second-order equation and intraparticle diffusion model can better describe the adsorption kinetics of di-(?-hydroxyethyl)aminobenzyliden-2-aminobenzothiazol onto titanium dioxide. |
