Özet
The photocatalytic activity of N-doped TiO2 particles supported on polystyrene (PS) surface by using a solvent-cast method at ambient temperature was evaluated on methylene blue (MB) dye decolourization. Subsequently, the effect of the new photocatalyst was evaluated in the inactivation of an antibiotic resistant (AR) Escherichia coli (E. coli) strain selected from the effluent of the biological process of an urban wastewater treatment plant. N-doped TiO2 particles supported on PS were characterized by UV vis DRS reflectance and Laser Raman spectra measurements. The results of photocatalytic tests with MB water solutions showed that MB can be successfully degraded (83-100%) under visible light after 180 min of irradiation. The system was also effective in the phenol photocatalytic degradation. Moreover, photocatalytic process effectively inactivated AR E. coil strain which was reduced by 97% after 30 min treatment. The developed preparation method could be a promising simple and low cost procedure for preparing immobilized photocatalysts for large scale commercial applications to wastewater treatment under direct solar light.
