Effect of KMP Stabilization on Chemical Properties of a Heavy-Metal Contaminated Site Soil

摘要：

　　This paper presents a comprehensive investigation of chemical properties,including soil pH,acid neutralizing capacity,metal leachability and chemical speciation,of a Zn,Pb and Cd contaminated site soil stabilized by KMP.The results show that the KMP stabilized soils have lower pH and higher resistance to acid attack than the untreated soil; the KMP is effective in reducing the metal leachability and changing the metal speciation,and the corresponding leached concentrations significantly below their regulatory limits; furthermore,lower acid soluble fraction contents contributes to the lower metal leachability in contaminated soils.
