Abstract

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.
