Mechanism and Factors of Transportation and Changing of Fluorine in Water & Soils in Yangshapao Reservoir
based on large quantities of investigation achievement from indoor experiments and field sampling analysis on water quality, the influencing factors of the changing of fluorine concentration is analyzed. The research finds out that condition of strong acid（pH≤6）can prevent the transportation of fluorine into water; condition of neutral or alkaline（pH≥6）is suitable for the transportation of fluorine, meanwhile, the condition of strong alkaline（pH≥8.9）is the best one for transportation of fluorine. The concentration of fluorine in water has a linear relation with HCO3 -, CO3 2-, and Na/Ca ratio, which means the more the ions are, the more the fluorine is. The soil with high content of fluorine in Western Jilin Province makes the fluorine transport from soil to water easily, and the alkaline environment also promotes the transportation of fluorine.
