چکیده
Background: This study examined the removal of ciprofloxacin (CIP), which is a very widely used antibiotic, from an aqueous medium by applying AgI/Ag۲O photocatalyst under visible light radiation. Methods: AgI/Ag۲O was synthesized conveniently by applying a two-stage precipitation method. The synthesized compound was characterized by X-ray powder diffraction (XRD), FE- field emission scanning electron microscopy (FE-SEM), energy dispersive x-ray (EDX), and UV-Vis spectrophotometry. Different parameters including initial pH of the solution, initial CIP concentration, reaction kinetics, and catalyst reusability were investigated. Results: Concurrent use of AgI and Ag۲O caused improved photocatalytic properties in the presence of UV light. The pH and initial concentration of CIP affected the process efficiency; ۹۵% efficiency was achieved within ۱۰۰ min at pH ۹. Furthermore, the process efficiency was still maintained over ۹۰% after four consecutive cycles. Conclusion: The photocatalytic degradation process using AgI/Ag۲O nanocomposite under visible light radiation is a suitable method for removing CIP from aqueous media due to its high efficiency and stability.کلیدواژه ها
