As an efficient and low cost adsorbent to remove fluoroquinolones antibiotics (such as ciprofloxacin and norfloxacin) in waste water, magnetic mesoporous carbon material has attracted increasing concern all over the world. Here, a convenient strategy to fabricate magnetic mesoporous carbon material has been explored with Fe containing metal-organic framework (MOF) as precursor. With this method, a magnetic mesoporous carbon material, Fe₃O₄/C , which possesses high surface area, is obtained through the calcination of a mixed valence Fe based MOF. For Fe₃O₄/C, its ciprofloxacin adsorption capacity reaches as high as 868.6 mg/g. Magnetic measurement reveals its ferromagnetic feature of Fe₃O₄/C with magnetization saturation 22.81 emu g−1 and this guarantees its excellent magnetic separation performance. Furthermore, Fe₃O₄/C also exhibits outstanding stability during ciprofloxacin containing waste water treatment.
