چکیده

Background and purpose: The aim of this study was to evaluate the efficiency of zinc oxidenanoparticles (ZnO NPs) in combination with US-H۲O۲ advanced oxidation processes (AOPs) for the removal of antibiotic amoxicillin (AMO) from aquatic environment. Materials and Methods: This experimental study was conducted in a batch reactor system. The effect of the parameters, such as pH (۳-۸), the dose of nanoparticles (۰.۰۱-۰.۰۸ g/L), reaction time (۱۰-۱۰۰ min), the initial concentration of the AMO (۱۵۰-۲۵۰ mg/L) and H۲O۲ (۰.۱ – ۵Mol/L) on the removal efficiency were studied in ultrasonic reactor. The residual AMO concentrations were measured at ۱۹۰ nm using a UV/Vis spectrophotometer. Results: The results showed that the US-H۲O۲ advanced oxidation processes using ZnO NPs can effectively lead to the removal of AMO from the wastewater. The optimal conditions for this process were pH ۳, ۰.۱ M of H۲O۲ and the dose ZnO NPs ۰.۰۵ g/L and time of ۶۰ minutes. In the current study, it was found that the removal efficiency dropped with the increasing concentrations of AMO. Under optimal conditions with ۱۵۰ mg/L of AMO and contact time of ۶۰ min, the efficiency removal was also equal to ۹۲.۴۷%. Conclusion: The results of this study showed that AOP was a very effective method that can be used for the removal of AMO antibiotic from aqueous solutions.
