Photodegradation of two pharmaceutical namely levofloxacin and atorvastatin via Chitosan/Ag/TiO2 3D printed scaffold

Pharmaceuticals are highly persistent towards hydrolysis, adsorption, biodegradation, and abiotic degradation .As a result, such pharmaceutical compounds are not effectively removed during sewage treatment. Furthermore, sewage effluents and hospital effluents are important point sources of pharmaceutical residues in surface water and groundwater . The potential impact of pharmaceutical residues on aquatic organisms and potentially humans through endocrine-disrupting effects or pathogenic bacteria developing antibiotic resistance. In this study the photooxidation of levofloxacin and atorvastatin was performed by chitosan/Ag/TiO₂ 3D printed scaffolds,  Ag nanoparticles elevated  the photocatalytic yields.  For maximum removals of levofloxacin and atorvastatin the optimum operational  conditions ( nanocomposit dose, pharmaceutical concentrations, photodegradation time, pH, temperature)  were researched. The reuse properties  and phys?cochemical properties of the Chitosan/Ag/TiO₂ 3D printed scaffolds  was also investigated.
