Study on the Diffusion Properties of Heavy Metal Copper Ion in Sandy Soil in Hangzhou, China

Abstract:

The diffusion properties of heavy metal copper ion are studied on sandy soil from Xiasha zone, Hangzhou city, China. The sandy soil is put into the large scale reaction tank in the laboratory, then compacted layer, and made to reach the degree of the natural density. The solution with concentration of copper sulfate is added into one end of the reaction tank, then the solution of the copper ion will diffuse into the sandy soil in the self-weight stress. Based on the adsorption content of the copper ion in the sandy, the diffusion regularity of the copper ion in the sandy soil is studied by the analytic test in the laboratory, and the diffusion mechanism of the copper ion is analyzed. Experimental results show that the adsorption contents of the copper ion in the sandy soil decreases with the increasement of the diffusion and the movement distance. Besides, the relationship between the adsorption contents of the heavy metal copper ion in the sandy soil and the diffusion and the movement distance can be formulated as an exponential function.
