In　this　study,　following　the　concept　of　＂treating　waste　with　waste＂,　magnetic　chitosan　carbon　(MCC)　was　developed　through　the　pyrolysis　of　chitosan/iron　sludge　(CHS)　beads　created　using　an　embedding　method　in　a　closed　environment　for　antimony　removal.　The　results　indicate　MCC　has　a　good　magnetic　recovery　rate　and　that　its　magnetic　saturation　strength　can　reach　33.243　emu/g.　The　iron　proportion　and　acid　resistance　of　MCC　were　all　better　than　those　of　CHS,　and　at　25　degrees　C,　its　adsorption　saturation　capacity　improved　from　24.956　mg/g　to　38.234　mg/g.　MCC　has　a　quick　adsorption　equilibrium　time,　and　in　about　20　min,　90%　of　the　final　equilibrium　capacity　can　be　achieved.　The　primary　mechanism　of　Sb　adsorption　by　MCC　is　the　formation　of　an　inner　sphere　complex　between　Fe-O　and　Sb,　while　surface　complexation,　hydrogen　bonding,　and　interaction　also　play　a　function.　Thus,　MCC,　a　lower-cost　and　greener　adsorbent　for　Sb　removal,　has　been　made　using　iron　sludge.　This　enabled　it　to　utilize　iron　sludge　as　a　resource　and　served　as　a　reference　for　the　sustainable　management　of　water　treatment　residuals.
