摘要：
Benzo[a]pyrene (BaP), one of the polycyclic aromatic hydrocarbons with potential carcinogenic, mutagenic and teratogenic toxicity, have been widely concerned. Herein, we report a simple and rapid co-precipitation method for the synthesis of magnetic covalent organic framework (Fe3O4/COF-DQTp) adsorbent for BaP removal. The magnetized COF-DQTp was characterized by fourier transform infrared, X-ray diffractometer, Brunauer-Emmett-Teller, vibrating sample magnetometer, transmission electron microscopy, high angle annular dark field scanning transmission electron microscopy image and energy-dispersive X-ray spectroscopy elemental mapping. Under the optimized adsorption conditions, the adsorption efficiency was as high as 99% and the maximum adsorption capacity is 19 mg/g in 10 min. The adsorption kinetics shows that adsorption of BaP onto Fe3O4/COF-DQTp follow pseudo-second order kinetic model. Moreover, the prepared Fe3O4/COF-DQTp has good reusability and is a potential material for the adsorption of BaP.
