This paper presents an evaluation of different dose of Sodium Metabisulfite (0.01 M Na₂S₂O₅), (Na₂S₂O₅) + (0.1 HCl), and Distilled water for the removal of soil contaminated with Pb, Zn and Cr by the column mode. The field soil contained concentrations of Pb (307.31 mg⋅kg⁻¹), Zn (207.77 mg⋅kg⁻¹) and Cr (447.50 mg⋅kg⁻¹). Both (0.01 M Na₂S₂O₅), (Na₂S₂O₅) + (0.1 HCl), and Distilled water were found to be effective on removing (Na₂S₂O₅) Pb, Cr and Zn respectively. (Na₂S₂O₅) + (0.1 HCl) Cr, Zn and Pb respectively. Sulfur Pb, Cr and Zn respectively. The removal rate of Pb, Zn, and Cr varied from 10.35% - 26%, 3.4% - 21.60% and 4.97% - 23.88% for (0.01 M Na₂S₂O₅ respectively. The removal rate of Pb, Zn, and Cr varied from 16.13% - 20.07%, 8.20% - 23.48%, 5.42% - 28.93% for (0.01 M Na₂S₂O₅ + 0.1 M HCl) respectively. The removal rate of Pb, Zn, and Cr varied from 10.20% - 25.5%, 9.55% - 25.13% and 6.04% - 25.54% for (S) respectively.
