摘要： 环丙沙星(CIP)作为典型抗生素，可破坏海洋微生物群落结构，对生态系统稳定性及人类健康构成严重威胁。铁酸锰(MnxFe3O4)结核纳米材料凭借其比表面积大、化学性质稳定、可快速磁分离的独特优势，其在CIP去除中的应用潜力为抗生素污染治理提供了新路径。本研究采用溶剂热法制备MnxFe3O4结核纳米材料，系统探究其对CIP的去除效能及关键影响因素。结果表明，在溶液pH 3~9、温度313.15 K左右及CIP中低初始浓度条件下，MnxFe3O4对CIP展现出最优去除效果；吸附动力学与吸附热力学证实，该吸附过程符合准二级动力学模型和Langmuir等温模型，吸附机制以化学吸附为主，且Langmuir模型计算得出其吸附容量达32 mg/g；热力学分析表明，MnxFe3O4对CIP的吸附过程均为自发进行。低成本制备的MnxFe3O4材料具有环境友好和高效稳定的特性，为环境中CIP污染的高效治理提供了可靠技术支撑，对保障生态环境安全具有重要实践价值。

Abstract: A common antibiotic contaminant, ciprofloxacin (CIP), can damage the structural integrity of marine microbial communities, endangering human health as well as the stability of marine ecosystems. Manganese ferrite nodular nanoparticles (MnxFe3O4) possess unique advantages including a high specific surface area, excellent chemical stability, and rapid magnetic separability. Accordingly, their significant potential for CIP removal provides a novel and promising strategy for the growing issue of antibiotic contamination in marine settings. In this study, MnxFe3O4 nodular nanoparticles were successfully synthesized via a solvothermal method, enabling precise regulation of the surface active sites, crystal structure, and morphology of the materials. The CIP removal performance of the synthesized MnxFe3O4 nanoparticles was systematically evaluated, and the key influencing parameters, including solution pH, reaction temperature, and initial CIP concentration, were clarified. Experimental results revealed that MnxFe3O4 exhibited the optimal CIP removal efficiency under the conditions of solution pH 3~9, reaction temperature of 313.15 K, and low-to-moderate initial CIP concentrations. Further adsorption kinetics and adsorption thermodynamics showed that the removal process was dominated by chemical adsorption,which well-fitted the Langmuir isotherm model and pseudo-second-order kinetic model. According to the Langmuir model, the maximum adsorption capacity of MnxFe3O4 for CIP was calculated to be 32 mg/g. Moreover, thermodynamic investigations verified that the adsorption of CIP onto MnxFe3O4 was a spontaneous process. Featuring low preparation cost, environmental friendliness, high efficiency, and stable performance, MnxFe3O4 nanomaterials provide reliable technical support for the efficient remediation of CIP contamination in aqueous environments and hold great practical value for ecological and environmental security protection.
