It has also been suggested that the oxidative treatment of OPSC with ,sulphuric acid, would introduce more acidic C=O groups on the surface of OPSC (Mostafa, 1997; Toles et al. 1999). This would enhance the electrostatic interaction between chitosan and the more negatively charged AOPSC and this prevents any tendency of chitosan to agglomerate.
