摘要：

This paper summarizes a case study involving a site with inorganic arsenic-contaminated soils. Detailed soil characterization studies involving sequential extraction testing indicated that the arsenic was primarily associated with the organic fraction and the iron oxide/manganese oxide fraction of the soil. A preliminary treatability study demonstrated that adequate leaching of arsenic was possible. Alkaline leaching was specific for arsenic. Future plans include a program of bench-scale treatability and field pilot studies focusing on soil washing technology application.
