Antibiotics　pose　significant　risks　to　both　the　environment　and　human　health.　Herein,　we　develop　a　collaborative　strategy　for　the　enhanced　removal　of　a　typical　antibiotic,　Ciprofloxacin　(CIP),　by　using　a　bamboo　leaf-derived　biochar/iron　silicate　composite　(BL-FeSi)　with　the　assistance　of　peroxymonosulfate　(PMS).　The　rationale　behind　the　design　is　the　construction　of　composited　material　with　synergistic　adsorption-catalysis　functions,　based　on　covalent　bonding　networks　of　the　biochar　and　specific　Fe(III)/Fe(II)　redox　chemistry　of　iron　silicate　in　PMS　activation　system.　H2　reduction　of　pristine　BL-FeSi　increases　Fe(II)　content　and　thus　improves　catalytic　activity.　Batch　experiments　demonstrate　that　the　preferred　BL-FeSi400　(H2　treatment　at　400　°C)　exhibits　superior　efficiency　in　activating　PMS.　The　CIP　removal　efficiency　is　highly　dependent　on　pH　value　of　reaction　solution.　A　remarkable　97%　removal　is　achieved　at　pH　=　5.5　(CIP:　60　mL,　20　mg/L;　BL-FeSi400:　0.2　g/L,　PMS:　0.2　g/L),　and　the　pH　increase　to　11　results　in　100%　CIP　removal.　The　BL-FeSi400　shows　robust　resistance　to　inorganic　ions　(NO3−,　SO42−,　HCO3−,　and　H2PO4−),　and　the　catalytic　activity　remains　consistently　high　(＞82%)　even　after　four　consecutive　cycles,　making　it　highly　promising　for　practical　applications.　It　is　found　that　both　radical　pathway　(•OH　and　SO4•−)　and　non-radical　pathway　(1O2)　contribute　to　CIP　degradation　in　the　BL-FeSi400/PMS　system,　while　the　active　•OH　dominates　the　oxidization　process.　The　coupling　of　adsorption　and　degradation　holds　great　potentials　for　effective　removal　of　more　organic　contaminants.　©　2024　The　Institution　of　Chemical　Engineers
