Equisetum diffusum D. Don was transplanted into solutions added with different concentrations of Mn, Zn, Cd, Pb, and As for 30 days in the laboratory experiment to assess the removal of these metals and their accumulation in the plant. The highest removal efficiency of Mn, Zn, Cd, Pb, and As from solutions by E. diffusum was 99.6, 97.9, 77.5, 85.3, and 61.9%, respectively. The highest daily removal efficiencies of heavy metals were obtained after 1 day of new solution addition. The highest concentrations of Mn, Zn, Cd, Pb, and As in the plant roots were 7230, 1490, 174, 1170, and 274 mg/kg-DW, respectively; those in the shoots were 1960, 566, 33.9, 308, and 108 mg/kg-DW. The bioconcentration factor (BCF) values for Mn, Zn, Cd, Pb, and As were 496, 406, 702, 463, and 191, respectively. The results of this study indicate that E. diffusum has the ability to remove simultaneously these metals from water, making it a potential species for phytoremediation of water contaminated with multiple heavy metals.

The electrokinetic remediation of an agricultural soil contaminated with heavy metals was studied using organic acids as facilitating agents. The unenhanced electrokinetic treatment using deionized water as processing fluid did not show any significant mobilization and removal of heavy metals due to the low solubilization of metals and precipitation at high pH conditions close to the cathode. EDTA and citric acid 0.1 M were used as facilitating agents to favor the dissolution and transportation of metals. The organic acids were added to the catholyte and penetrated into the soil specimen by electromigration. EDTA formed negatively charged complexes. Citric acid formed neutral metal complexes in the soil pH conditions (pH = 2–4). Citric acid was much more effective in the dissolution and transportation out of the soil specimen of complexed metals. In order to enhance the removal of metals, the concentration of citric acid was increased up to 0.5 M, resulting in the removal of 78.7% of Cd, 78.6% of Co, 72.5% of Cu, 73.3% of Zn, 11.8% of Cr and 9.8% of Pb.
