Heavy metal cadmium , copper and zinc were used to study single and the effect of five different redox potential for transport amounts through an outflow experiment using saturated soil column. The results indicate that oxidizing conditions in the soil, the sequence of the cadmium in the BTCs was Eh = 490mv> 350mv> 240mv. Reducing conditions in the soil, the sequence of the cadmium in the BTCs was Eh = 490mv> 350mv> 240mv. In oxidizing conditions, high redox potential of soil can significantly promote the transport of copper. In reducing conditions, low redox potential of soil can inhibit the transport of copper, which has nothing to do with the reducing agent concentration. The BTCs peak value of zinc in the highly oxidized conditions were significantly higher than the lowly oxidation conditions; and the effect of different reduction conditions for transport of zinc is not obvious. The transport of three heavy metals ions cadmium , copper and zinc in the flow of liquid pH value decreased, then increased and final equilibrium, the flow of fluid oxidizing condition of the soil pH value is less than reducing conditions; and Eh value of just the opposite.
