Abstract [en]

The adsorption mechanism of poly(1-vinyl-2-pyrrolidone) (PVP) and azelaic acid on synthetic γ-aluminium oxide surfaces was investigated using FT-IR spectroscopy. It was found that PVP adsorption from both aqueous and ethylene glycol (EG) solutions, was negligible, but the presence of the dicarboxylic acid enhances the adsorption of the PVP, due to a hydrophobic interaction between the carbon chains of the polymer and the dicarboxylic acid. The carbon chain of the adsorbed dicarboxylic acid is lateral to the surface and attached to it by both carboxylic groups. The simultaneous adsorption of PVP and azelaic acid was studied as a function of time, pH, solvent and ionic strength of the suspension in order to establish a more detailed surface complexation model. Three main surface complexes were found on the surface of the γ-alumina at low pH in aqueous as well as in EG solutions, while at high pH one of them namely the outer-sphere complex dominates.
