Research on the migration behavior of Cypermethrin in the leaching experiment by soil column
In this paper, engaged the soil column and choiced Cypermethrin as tracer, the breakthrough behavior of tracer in different porous media was studied., and discussed the influence of the longitudinal dispersion coefficient of Cypermethrin by the characteristics of the porous medias.leaching experiments simulated natural rainfall intensity as leaching intensity, compared breakthrough curves of cypermethrin and chloride ion by changing the filled medium.The results show that the breakthrough curves of cypermethrin and chloride ion are very close which mean the cypermethrin have higer transport properties in water and have a certain threat to pollute groundwater.The content of soil organic matter is higher the diffusion coefficient is lower.The leaching intensity which choice by the experiment has little effect on the diffusion coefficient of cypermethrin.
