In　the　present　work,Ce-La-MOFs@F3O4　composites　were　prepared　via　hydrothermal　method,and　the　adsorption　performance　of　Ce-La-MOFs@Fe3O4　on　F-　in　aqueous　solution　was　investigated,and　the　adsorption　conditions　were　optimized　by　response　surface　method.　The　experimental　results　show　that　the　best　adsorption　effect　of　Ce-La-MOFs@Fe3　O4　is　achieved　at　pH　=　3.　6,experimental　temperature　of　40　℃,　and　initial　fluoride　ion　concentration　of　17.　4　mg　/　L,and　the　F-　removal　efficiency　could　reach　94.　5%.　The　experimental　datas　of　fluoride　removal　were　more　suitable　to　be　described　by　Langmuir　isotherm　model,and　the　maximum　adsorption　capacity　(qmax)is　147.　23　mg　/　g.　The　thermodynamic　parameters　ΔGo,ΔHo　and　ΔSo　indicated　that　the　adsorption　reaction　is　anentropy-increasing　process　with　spontaneous　heat　absorption,　and　kinetic　study　show　that　the　adsorption　of　F-　by　Ce-La-MOFs@Fe3　O4　is　well　fitted　with　the　pseudo　second　order　model.　The　morphology　and　structure　of　the　composites　were　characterized　and　analyzed,and　the　adsorption　mechanisms　were　explored　in　conjunction　with　the　adsorption　thermodynamic　and　kinetic　studies,which　were　mainly　a　combination　of　ion-exchange　action　and　electrostatic　adsorption.　The　results　of　co-existing　ion　experiments　and　regeneration　experiments　show　that　Ce-La-MOFs　@　Fe3　O4　has　ahigh　selectivity　for　F-　.　And　the　regeneration　performance　of　Ce-La-MOFs　@　Fe3　O4　is　so　excellent　that　the　recovery　rate　can　reach　96%.　After　two　cycles,the　removal　efficiency　still　reached　81.　74%　of　F-　©　2024　Cailiao　Daobaoshe/　Materials　Review.　All　rights　reserved.
