ZnFe2O4/AC　composites　were　prepared　by　a　one-pot　hydro-thermal　method　using　the　activated　carbon　as　a　carrier.　The　structural,　textural　and　surface　properties　of　the　adsorbent　have　been　comprehensively　characterized　by　scanning　electron　microscopy　(SEM),　X-ray　diffraction　(XRD),　Raman　spectra,　physical　adsorption　instrument　(BET)　and　TG-DSC　analysis.　The　removal　capacities　of　the　composites　were　investigated　via　testing　the　adsorption　capacity　at　the　self-made　desulfurization　equipment.　The　process　of　adsorption　for　SO2　was　analysed　by　kinetic　model　and　thermodynamic　model.　The　results　show　that　the　adsorption　capacity　of　ZnFe2O4/AC　composites　adsorption　kinetics　process　was　conformity　with　the　first　kinetics　mode1.　The　adsorption　process　was　in　accordance　to　the　Langmuir　and　Freundlich　equation.　Additionally,　the　whole　process　belonged　to　spontaneous　and　exothermic　reaction.
