摘要：
This paper reviews current progress and technologies of removal of chromium (Cr) from soil by washing with chelants. The applications of soil washing with chelants are noted; the major controlling factors in soil washing process are discussed; the mechanism of removal of Cr in soil using chelants is reviewed. Soil washing is one of the few permanent treatment alternatives to remove metal contaminants from soils. The chelant reagent has the most influence on washing effect.
