| Περίληψη: | Recently the synthesis and application of bio-based composite materials which contain polymeric and inorganic units such as TiO2 has gained much attention in the field of water/wastewater treatment, due to their better and more practical performance parameters. In the present study, floating polymer supported nanocomposites consisting of biobased chitosan (CS), graphene oxide (GO) and TiO2 nanoparticles were prepared and investigated for the removal of target cytostatic/ antineoplastic drug mixture (cyclophosphamide, 5-flourorouracil, tamoxifen, and cytarabine) in aqueous solution. The final concentrations of TiO2/GO in CS were 5, 10, 15 and 20 wt%. The synthesized photocatalysts were characterized using Fourier Transform Infrared spectroscopy (FTIR) and wide-angle X-ray diffraction (WAXD). The photocatalytic experiments were carried out under simulated solar irradiation (SSL). The effect of various factors such as variation of pH, catalyst concentration and initial substrate concentration, as well as reaction kinetics were investigated. An increase at the photocatalytic rate of cytostatic/ antineoplastic drugs was observed at higher concentrations of TiO2/GO in CS. However, at higher concentrations of TiO2/GO, the hydrophilicity of the materials increases, leading to possible decomposition. Finally, the transformation products (TPs) generated during the photocatalytic treatment were investigated using liquid chromatography coupled to high resolution mass spectrometry, while mineralization was also followed by ion chromatography and total organic carbon measurements. |
