Abstract

In this paper, it is attempted to study the capacity of blast furnace to stabilize cr(VI)-contaminated soils. The slag samples are incorporated with soils in different proportions and the resulted leachate is tested using batch and column experiments to simulate static and dynamic flows. furthermore, the mechanism by which the chro-mium in the soil is reduced by the iron slag is discussed. The study demonstrated that blast furnace slag can effectively stabilize cr(VI)-contaminated soils.
