An　economical　corncob　biochar-based　magnetic　iron-copper　bimetallic　nanomaterial　(marked　as　MBC)　was　successfully　synthesized　and　optimized　through　a　co-precipitation　and　pyrolysis　method.　It　was　successfully　used　to　activate　H2O2　to　remove　ciprofloxacin　(CIP)　from　aqueous　solutions.　This　material　had　high　catalytic　activity　and　structural　stability.　Additionally,　it　had　good　magnetic　properties,　which　can　be　easily　separated　from　solutions.　In　MBC/H2O2,　the　removal　efficiency　of　CIP　was　93.6%　within　360　min　at　optimal　reaction　conditions.　The　conversion　of　total　organic　carbon　(TOC)　reached　51.0%　under　the　same　situation.　The　desorption　experiments　concluded　that　adsorption　and　catalytic　oxidation　accounted　for　34%　and　66%　on　the　removal　efficiency　of　CIP,　respectively.　The　influences　of　several　reaction　parameters　were　systematically　evaluated　on　the　catalytic　activity　of　MBC.　OH　was　proved　to　play　a　significant　role　in　the　removal　of　CIP　through　electron　paramagnetic　resonance　(EPR)　analysis　and　a　free　radical　quenching　experiment.　Additionally,　such　outstanding　removal　efficiency　can　be　attributed　to　the　excellent　electronic　conductivity　of　MBC,　as　well　as　the　redox　cycle　reaction　between　iron　and　copper　ions,　which　achieved　the　continuous　generation　of　hydroxyl　radicals.　Integrating　HPLC-MS,　ion　chromatography　and　density　functional　theory　(DFT)　calculation　results,　and　possible　degradation　of　the　pathways　of　the　removal　of　CIP　were　also　thoroughly　discussed.　These　results　provided　a　theoretical　basis　and　technical　support　for　the　removal　of　CIP　in　water.
