With the aid of soil column test models, the transport regularity of fluoride in different polluted fluoride soils of Yuncheng Basin was studied. Laboratory experiments reveal that the migration process of fluorine ion in soils is complex because of its active chemical properties. The pH values of the soil solution change from neutral to alkaline due to the release of OH-resulting from the adsorption in the course of the experiment. The migration distance in vertical direction is comparatively short, and hence it is very difficult for the F- ion to migrate directly from soil to groundwater through eluviation. The results are consistent with the observation data.
