The　performance　of　a　Ce(III)-4,4　＇,4　＇＇-((1,3,5-triazine-2,4,6-triyl)　tris　(azanediyl))　tribenzoic　acid-organic　framework　(Ce-H3TATAB-MOFs)　for　capturing　excess　fluoride　in　aqueous　solutions　and　its　subsequent　defluoridation　was　investigated　in　depth.　The　optimal　sorption　capacity　was　obtained　with　a　metal/organic　ligand　molar　ratio　of　1:1.　The　morphological　characteristics,　crystalline　shape,　functional　groups,　and　pore　structure　of　the　material　were　analyzed　via　SEM,　XRD,　FTIR,　XPS,　and　N-2　adsorption-desorption　experiments,　and　the　thermodynamics,　kinetics,　and　adsorption　mechanism　were　elucidated.　The　influence　of　pH　and　co-existing　ions　for　defluoridation　performance　were　also　sought.　The　results　show　that　Ce-H3TATAB-MOFs　is　a　mesoporous　material　with　good　crystallinity,　and　that　quasi-second　kinetic　and　Langmuir　models　can　describe　the　sorption　kinetics　and　thermodynamics　well,　demonstrating　that　the　entire　sorption　process　is　a　monolayer-governed　chemisorption.　The　Langmuir　maximum　sorption　capacity　was　129.7　mg　g(-1)　at　318　K　(pH　=　4).　The　adsorption　mechanism　involves　ligand　exchange,　electrostatic　interaction,　and　surface　complexation.　The　best　removal　effect　was　reached　at　pH　4,　and　a　removal　effectiveness　of　76.57%　was　obtained　under　strongly　alkaline　conditions　(pH　10),　indicating　that　the　adsorbent　has　a　wide　range　of　applications.　Ionic　interference　experiments　showed　that　the　presence　of　PO43-　and　H2PO4-　in　water　have　an　inhibitory　effect　on　defluoridation,　whereas　SO42-,　Cl-,　CO32-,　and　NO3-　are　conducive　to　the　adsorption　of　fluoride　due　to　the　ionic　effect.
