Dynamic experimental study on transport law of F-in soils

Transport of chemicals in soils could be influenced by some soil factors,such as soil moisture,texture,homogeneity,soil temperature,characteristic of chemicals and the way of inputting solute and so on.The influence of the texture and the way of inputting solute on transport of chemicals under the laboratorial conditions were studied.It was shown that the value of the hydraulic dispersion coefficient and the retardation factor in soil(mixture of sand and kaolin) was greater than that in sand,and the inputting of sodium chloride influenced transport rule of F-in different soils.
