Ezperiment Study of Fluoride Desorption with Groundwater Infiltration in Soil
Fluoride contamination transport and adsorption study is a hot subject of soil environment research. Dynamic adsorption, desorption and kinetics study can help us deeply understand the migration and transformation mechanism of fluoride in water and soil system, and provide theoretical basis for environmental assessment and treatment. This paper reveals the fluoride desorption law with the infiltration of groundwater. It concluded that vertical distribution and desorption process of fluoride ions is different with content of clay and grain diameter. It is not a simple linear process for the decreasing concentration of fluoride. As in practical engineering application, we should make a special water import project for fluoride dilution according to the soil properties.
