Research evidence has shown that pollution of surface and underground waters is the leading sources of environmental and health-related problems. Disposed unused therapeutic drugs have been known to contaminate underground water and also offer drug resistance to infection-causing bacterial. This research seeks to evaluate the use of US/PS/Fe₃O₄ for the removal of ciprofloxacin (CIP-F) from aqueous solutions. The research also seeks to obtain the optimum set of conditions about which the highest removal efficiency of CIP-F is obtained by monitoring the used pH, Fe₃O₄ nanoparticles (NPs) concentration, PS concentration, CIP-F concentration, and contact time. The analysis was done using a UV–Vis spectrophotometer (Cecil model CE102) set at 280 nm. The result shows that a 98.43% removal efficiency is achievable after optimization if the separation parameters were set to the optimum conditions (pH = 5, CIP-F concentration = 200 mg/L, PS concentration = 0.15 mol/L, Fe₃O₄ concentration = 0.01 g/L and contact time = 45 min). The reaction was also observed to follow the pseudo-first-order reaction model. Since the results obtained show that US/PS/Fe₃O₄ can effectively and efficiently aid the surface adsorption of CIP-F from aqueous solutions, it is therefore recommended based on experimental findings that US/PS/Fe₃O₄ be used for removing CIP-F from effluents.

基于过硫酸盐的高级氧化工艺（US / PS / Fe 3 O 4）去除水溶液中环丙沙星的功效

研究证据表明，地表水和地下水污染是与环境和健康有关的问题的主要根源。已知已弃置的未使用的治疗药物会污染地下水，并且还对引起感染的细菌具有耐药性。这项研究旨在评估US / PS / Fe ₃ O ₄用于从水溶液中去除环丙沙星（CIP-F）的用途。该研究还寻求通过监测所用的pH，Fe ₃ O ₄来获得最佳条件，从而获得最高的CIP-F去除效率。纳米颗粒（NPs）浓度，PS浓度，CIP-F浓度和接触时间。使用设置在280 nm的UV-Vis分光光度计（Cecil型号CE102）进行分析。结果表明，如果将分离参数设置为最佳条件（pH = 5，CIP-F浓度= 200 mg / L，PS浓度= 0.15 mol / L，Fe ₃ O _4），则优化后去除率可达98.43％。浓度= 0.01 g / L，接触时间= 45分钟）。还观察到该反应遵循伪一级反应模型。由于获得的结果表明US / PS / Fe ₃ O ₄可以有效和有效地帮助CIP-F从水溶液中吸附表面，因此，基于实验结果，建议使用US / PS / Fe ₃ O ₄从废水中去除CIP-F。
