Abstract Chelating agents and acids were evaluated for removing heavy metals from contaminated soils. Two soils, latosols soil and sandatone-shale alluvial soil, artificially contaminated with Cu, Zn, and Pb were investigated. The removal efficiencies of Cu, Zn, and Pb from both soils for various chelating agents and acids followed the descending order EDTA > DTPA > Citric Acid > HCl.
