Description
Summary:Chitosan/TiO2 nanocomposite was fabricated by a film-casting method for the adsorption of Congo red. The nanocomposite film was characterized by Fourier transform infrared spectroscopy, field-emission scanning electron microscopy, powder X-ray diffraction, thermogravimetric analysis, weight-loss test, and adsorption study. Morphological analysis revealed rough and agglomerated filler materials over the film surface. The interaction among components of the composite was proven by powder X-ray diffraction and Fourier-transform infrared spectroscopy. The weight-loss result showed excellent stability of the composite in acidic medium. The adsorption mechanism was supported by both Langmuir and Freundlich isotherm models. The adsorption capacity of the composite film was 32 mg/g.
