Experimental study and numerical simulation of fluoride in sand1

The transport and transformation of fluoride in sand were studied by using soil tank test under the condition of saturated water in this article. Based on the analysis of the laboratory experiments, the rules of fluorine transportation and transformation were simulated in sand by solving the advection-diffusion equation. Through comparison between computed results and observed data, it is shown that the established model and determined parameters could be used to simulate the fluoride transport in sand.
