Magnetic　covalent　organic　framework　modified　by　Fe3O4　nanoparticles　(Fe3O4@COF)　were　facile　synthesized　and　used　as　adsorbent　for　the　adsorption　of　bisphenols　from　aqueous　solutions.　The　Fe3O4@COF　is　synthesized　by　catalyst-free　Schiff　base　reaction　of　melamine　and　terephthalaldehyde,　and　synthesis　strategy　is　flexible　and　controllable.　The　as　prepared　Fe3O4@COF　was　characterized　by　TEM,　PXRD,　TGA　and　BET　analysis.　The　Fe3O4@COF　possessed　large　specific　surface　area　(3352　m(2)/g),　high　chemical　and　thermal　stability,　and　high　saturation　magnetization　(49.6　emu/g),　which　in　favor　of　rapid　magnetic　separation　and　efficient　adsorption　in　the　adsorption　process.　The　effects　of　temperature,　adsorbent　dosage,　pH　and　salt　concentration　on　the　adsorption　of　bisphenols　(BPA　and　BPAF)　were　studied.　The　as-prepared　adsorbent　showed　an　excellent　adsorption　ability　for　BPA　and　BPAF,　and　the　max　adsorption　capacity　of　BPA　and　BPAF　could　reach　140　and　290.4　mg/g.　The　adsorption　kinetic　fitted　the　pseudo-second-order　kinetic　model　and　the　adsorption　isotherm　followed　the　Freundlich　isotherm　equation.　Moreover,　the　Fe3O4@COF　presented　favorable　re-use　performance,　which　kept　over　81.4%　removal　efficiency　of　bisphenols　after　five　consecutive　recycles.　The　high　adsorption　performance　and　reusability　make　the　Fe3O4@COF　a　promising　adsorbent　for　the　removal　of　bisphenols.　(C)　2020　Elsevier　B.V.　All　rights　reserved.
