Abstract：Objective：Tomodifyandprepareactivatedcarbonfortheremovalofperfluorinatedpolutantsinlakewater，andexplore itsperfluorinatedpolutantremovalpeformance.Method：Sludgeispreparedfromdomesticsewage，andthenlanthanumloadedsludge based modified activated carbon is produced.Conduct adsorption experiments on lake water samples in a 23% constant temperature water bath to determine the content of PFOS，PFOA，and PFHxS.Result：After the loading of lanthanum reached 30% ，the growth rate of removal rate slowed down．When the reaction time is 8 hours and the lanthanum loading is 30% ， 60g of activated carbon can completely adsorb perfluorinated pollutants in 200mL of water sample，indicating that activated carbon has strong adsorption capacity for perfluorinatedpolutantsndcanbeusedtotreatlakewatecontaingperfuoiatedpolutants.Teremoalateisotialatp.Cocusion： Byoptimizingtheconditions，lanthanumladedsudgebsedmodifiedactivatedcarboncansignificantlyremovepefuornatedpolutants， providing an effective solution for lake water purification and having practical value.
