Abstract
- Because the slag can be a major source of soil and groundwater pollution, understanding the release and leaching behavior of hexavalent chromium [Cr(VI)], from chromium-containing slag is critical. We report Cr(VI) behavior after static and dynamic leaching from chromium-containing slag deposited at a ferro-alloy manufacturing plant in Hunan province, China. Bench-scale experiments indicate that the main factors influencing the dissolution release of Cr(VI) include the solid-liquid ratio, soak time, agitation, acidity, particle size, and water dynamic flow. Based on the parameters obtained from the dynamic leaching experiment, a Cr(VI) release and leaching model was developed and applied to the study area. The model can quantitatively predict the extent of Cr(VI) pollution of soil and groundwater under atmospheric precipitation. [ABSTRACT FROM AUTHOR]
