The　photoresponsive　adsorption　materials　are　of　great　significance　to　the　light　controlled　release　performance　of　pollutants　and　the　development　of　green　regeneration　of　adsorption　materials.　A　photoresponsive　cellulose　based　imprinted　adsorbent（Cell-AB-MIP）was　synthesized　by　surface-initiates　atom　transfer　radical　polymerization　（SI-ATRP）　using　cellulose　as　raw　material，azobenzene　derivatives　as　functional　monomers，and　the　typical　pesticide　residues　2，4-D　as　template.　The　synthetic　conditions　were　optimized　by　single　factor　experiment　，and　the　structure　and　performance　of　the　material　was　analyzed　by　some　characterization　methods.　The　results　show　that　the　surface　of　Cell-AB-MIP　contains　abundant　functional　groups（—COOH，N=N，etc.），which　have　a　high　specific　recognition　effect　for　2，4-D.　The　introduction　of　azobenzene　group　makes　Cell-AB-MIP　have　excellent　photo-induced　regeneration　performance.　The　azobenzene　group　on　Cell-AB-MIP　surface　changes　from　trans-configuration　to　cisconfiguration　under　UV　irradiation，then　changing　the　binding　affinity　of　adsorbent　for　pollutants，thus　realizing　green　regeneration　via　UV-light.　The　desorption　efficiency　can　reach　72.　22%　in　methanol　medium　under　UV　light　irradiation.　After　5　times　of　cycle，the　adsorption　percentage　to　2，4-D　still　remains　83.　47%.　The　analysis　results　of　SEM　and　EA　confirm　that　the　adsorbed　pollutants　can　be　separated　from　the　surface　of　the　adsorbent　after　UV　irradiation，completing　the　regeneration　process.　©　2024　Beijing　Institute　of　Aeronautical　Materials　(BIAM).　All　rights　reserved.
