Abstract [en]

A laboratory study is conducted to test the capacity of two types of iron slag to stabilize Cr(VI)-contaminated soils. The slag samples are incorporated with soils in different proportions and the resulting leachate is tested using batch experiments. The feasibility of using iron is demonstrated as concentrations up to 1000 mg Cr(VI)/kg in the leachate of an alkaline soil are reduced to 0,7 mg Cr(VI)/kg mix after 12 days, but to less than 5 mg Cr(VI)/kg mix after 7 days. Small particles size and L/S-ratio are, in most cases, favoured by the reducing agents to stabilize the contaminated soil. The study demonstrated that the iron slag can effectively stabilize Cr(VI)-contaminated soils.
