In this work, a new facile one-spot method has been designed to fabricate a magnetic recyclable FeO/rice husk biochar photocatalyst (FBP) for the removal of Ciprofloxacin (CIP) in aqueous solution. This method combines ultrasonic-assisted impregnation and precipitation, which can overcome the difficulties of long-time reactions, complex procedures, and extreme condition requirements. The successful fabrication of the FeO/biochar material has been proven by a series of material characterization techniques, including X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Raman, Fourier Transform Infrared Spectroscopy (FTIR), X-ray Photoelectron Spectroscopy (XPS), and vibrating sample magnetometer (VSM). Moreover, the as-product FBP exhibited the excellent ability of photodegrading CIP and the possibility of magnetic recovery from the aqueous solution, suggesting a potential solution for removing antibiotic pollutants in environmental remediation.
在本研究中，设计了一种新型简便的一步法来制备磁性可回收的FeO/稻壳生物炭光催化剂（FBP），用于去除水溶液中的环丙沙星（CIP）。该方法结合了超声辅助浸渍和沉淀法，可克服长时间反应、程序复杂和极端条件要求等困难。通过一系列材料表征技术，包括X射线衍射（XRD）、扫描电子显微镜（SEM）、拉曼光谱、傅里叶变换红外光谱（FTIR）、X射线光电子能谱（XPS）和振动样品磁强计（VSM），证明了FeO/生物炭材料的成功制备。此外，所制备的FBP表现出优异的光降解CIP的能力以及从水溶液中磁回收的可能性，为环境修复中去除抗生素污染物提供了一种潜在的解决方案。
