Nowadays antibiotics are one of the most widely used drugs with a high amount of release in nature and a major contribution to environmental pollution. Activated carbon is one of the most widespread adsorbents of these contaminants, but the main drawback to the use of this material is the difficulty of separation from the environment. In this study, we presented a straightforward and biocompatible method for preparation of carbon-based nanocomposite containing cobalt ferrite for use in wastewater treatment. Cobalt ferrite and silver nanoparticles were synthesized on the carbon templates by a hydrothermal method as a green procedure. In this work, grapefruit extract was used to make activated carbon powder. The prepared products were characterized by X-ray Diffraction pattern (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Ultraviolet–Visible absorption (UV–Vis), Energy Dispersive X-ray (EDX), and Fourier Transform Infrared spectroscopy (FT-IR). Vibrating Sample Magnetometer (VSM) was used to study the magnetic properties of the products. New magnetic C@CoFe₂O₄@Ag nanocomposite was successfully examined for removal of penicillin and ciprofloxacin from aqueous solutions. Because of the presence of silver on the C@CoFe₂O₄@Ag, it also showed photocatalyst property in the photo-degradation of organic pollutants.

如今，抗生素是最广泛使用的药物之一，它在自然界中具有很高的释放量，并且对环境污染有重大贡献。活性炭是这些污染物最广泛的吸附剂之一，但使用这种材料的主要缺点是难以与环境分离。在这项研究中，我们提出了一种简单且生物相容的方法，用于制备用于废水处理的含钴铁氧体的碳基纳米复合材料。通过水热法以绿色程序在碳模板上合成了钴铁氧体和银纳米颗粒。在这项工作中，葡萄柚提取物被用来制造活性炭粉。制备的产物通过X射线衍射图（XRD），扫描电子显微镜（SEM），透射电子显微镜（TEM），紫外可见吸收（UV-Vis），能量色散X射线（EDX）和傅立叶变换红外光谱（FT-IR）。振动样品磁强计（VSM）用于研究产品的磁性能。新型磁性C @ CoFe成功地检测了₂ O ₄ @Ag纳米复合材料从水溶液中去除青霉素和环丙沙星的能力。由于在C @ CoFe ₂ O ₄ @Ag上存在银，它在有机污染物的光降解中也表现出光催化性能。
