Abstract The column experiments and numerical simulations were conducted to evaluate effects of redox potentials (Eh) on the transport of cadmium (Cd), zinc (Zn), and copper (Cu) in soils. The results showed that the competitive adsorption capacity of Cu was greater than that of Cd and Zn, resulting in a lower mobility in the soil under different redox potentials. Due to the competitive adsorption of Cd, Zn, and Cu, the "snow plow effect" takes place, resulting in the higher concentrations of Cd and Zn in the effluents than in the input. Compared to the control, both the increase and decrease in Eh promote the transport rate of Zn and Cd, but have different impacts on recovery rate. With an increase in Eh, the transport of Cu can be promoted in the soil. The good performance of TSM and OSM models for simulating the transport behavior of heavy metals further confirms that the adsorption of heavy metals in soils is time-limited (f < 0.7). In general, both the influence of redox potential and the concentration superimposition caused by heavy metal competitive adsorption should be considered in the evaluation and prevention of heavy metal compound contaminated soils.

Key words： heavy metal redox potential adsorption soil snow plow effect numerical simulation
