摘要
In this study, the CoFe2O4/hexagonal boron nitride (h-BN) nanocomposite prepared via the microwave irradiation method, was hybridized with the MIL-53 (Al) metal–organic framework. The structure and morphology of the magnetic CoFe2O4/h-BN/MIL-53(Al) nanocomposite were investigated using Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray analyzer (EDX), Brunauer-Emmett-Teller (BET) surface area analysis, vibrating sample magnetometry (VSM) and zeta potential analysis. The adsorption performance of the CoFe2O4/h-BN/MIL-53 (Al) nanocomposite as a magnetically recyclable adsorbent for removing tetracycline (TC) and ciprofloxacin (CIP) antibiotics in aqueous solutions was investigated under different influence factors, including contact time, initial drug concentration, adsorbent dosage, pH conditions, temperature and ionic strength. The results indicated that the nanocomposite adsorbed 100 % of drugs within a short time (20–––30 min), with a maximum adsorption capacity of 625.00 mg g-1and 270.27 mg g−1, respectively. Additionally, the adsorption mechanism was also discussed based on the obtained results. After the drug absorption and removal process, the nanocomposite can be easily separated and reused several times without losing its absorption activity, therefore making it an appropriate choice for removing drugs from polluted water.
