This study presents the efficiency of treatment of heavy metal in contaminated soil by 04 solvents. The results show that EDTA.2Na 0.2% solvent in water is the most suitable choice for the treatment of heavy metal by soil washing. The efficiency of treatment Pb, Cd, Cu, and Zn reached over 90%, Cr reached over 70%, and As over 60%. The results also indicated that the solvents play an important role in eliminating heavy metals by soil washing techniques.
