As　anthropogenic　antibiotics,　quinolones,　e.g.,　ofloxacin　have　adverse　impacts　on　ecological　systems　and　human　heaths.　The　removal　of　quinolones　is　of　great　importance,　and　adsorption　techniques　have　been　widely　used　to　remove　this　hazardous　contaminant.　However,　a　robust　and　easy-operating　adsorbent　is　still　emergently　required　due　to　the　complex　chemical　structure　of　quinolones.　In　this　study,　we　successfully　synthesized　the　promising　metallic　carbons　(MCs)　containing　carbon　nanotubes　and　cobalt　nanoparticles　by　carbonizing　Zn/Co-ZIF　at　900　degrees　C.　Three　different　molar　ratios　of　Co　and　Zn　were　applied　to　optimize　the　adsorption　capacity　on　ofloxacin　(OFL).　Results　showed　MC　with　molar　ratio　of　Co　and　Zn　at　3:1　(Co-CNT/NPC3/1)　achieved　the　maximal　adsorption　capacity　to　118.3　mg　g-1.　Its　adsorption　performance　was　satisfied　in　the　pH　range　from　5　to　9　and　ionic　strengths　at　0.01　M.　The　main　mechanisms　for　these　adsorptions　were　identified　as　electrostatic　attraction,　metal　coordination　and　pi-pi　EDA.　Removal　efficiencies　of　quinolones　higher　than　68　mg　g-1　indicated　the　strong　feasibility　of　this　adsorbent　for　wastewater　treatments.　The　regeneration　of　Co-CNT/NPC3/1　at　600　degrees　C　allowed　its　at　least　4-time　reusability　and　its　magnetic　property　enabled　external　magnets　to　recycle　it　from　real　environments.
