Synthesis, Characterization, and Evaluation of Degussa P25/Chitosan Composites for the Photocatalytic Removal of Sertraline and Acid Red 18 from Water

Abstract Degussa P25 titanium dioxide/chitosan composites (P25/CS) were prepared using three different methods and two chitosan materials. The obtained materials characterized by diffuse reflectance UV–Vis, Fourier-transform infrared spectroscopies, X-ray diffraction, scanning electron microscopy. It was observed for all that the surface is homogeneously covered P25, particles are evenly dispersed on whole matrix do not form agglomerates. performance of P25/CS tested in water treatment photocatalytic reaction sertraline Acid Red 18. results show application effective decomposition model organic impurities water. Moreover, presence considerably facilitates separation catalyst from mixture, which a great advantage compared to pure P25. preparation method did major effect activity. glutaraldehyde as crosslinking agent simplest one; thus, it recommended P25/chitosan nanocomposites preparation. These can be successfully applied purification degradation pollutants. Graphic
