Abstract: The stabilization effects of active carbon material on copper in copper and cadmium combined contaminated soils by static desorption experiment were discussed in order to realize the safe utilization of the soils. Four kinds of tested soils, iatosolic red soil, zheltozem, yellow brown soil and red soil namely, were prepared as sole/combined contaminated soils with chemical solvents. The results indicated there was significant synergy between copper and cadmium in combined contaminated soil, compared with sole contaminated soil. So the copper concentration in the balance solution in the combined contaminated soil was higher than that in sole contaminated soil. The stabilization rate of active carbon to copper was from 52% to 74% by static desorption experiments when the dose of carbon materials was both 5% of soil weight because active carbon was abundance of specific surface area and surface functional group. In addition, the stabilization results on copper were affected by the content of organic materials, not by cadmium.
