摘　　要：针对吉林西部花敖泡、道字泡、大布苏泡等湖泊水体及底泥中氟污染严重情况,利用土壤的连续分级浸提法,分别在天然状态下及不同pH下将吉林西部湖泊底泥中的氟逐级提取,依次为水溶态氟、可交换态氟、铁锰结合态氟、有机束缚态氟及残余态氟。研究吉林西部湖泊底泥中氟赋存形态及主要影响因素,并基于pH对底泥中不同形态氟分布的影响来研究底泥氟在水土体系中的迁移转化行为。The mud samples were collected from 3 lakes of Huaaopao,Daozipao,Dabusupao,which all located at western of Jilin province.In order to find out the contaminative conditions of fluorine in water body and mud of these lakes,the experimental of sequential filtering extraction was applied to extract different forms of fluorine from lake mud under the natural state and different pH level.The fluorine was divided into water-soluble fluorine,exchange fluorine,iron-manganese combined fluorine,organic fluorine and residual fluorine respectively.Fluorine existing status in lakes of western Jilin and the influencing factors were studied.The effect of pH on fluorine distribution was analyzed,base on which,the behavior of fluorine migration and transfer in the soil and aquatic environment was revealed.
