Abstract

Electrokinetic soil remediation is an innovative method for DECONTAMINATION of heavy metals from polluted soils. In this research a clayey soil spiked with Zn at the concentration of 350 mg/kg used to investigate ELECTROKINETIC REMEDIATION at pilot-scale with different treatments. NITRIC ACID (0.1 M), ACETIC ACID (0.1 M), EDTA (0.01 M) and deionized water (at the two different applied initial electrical current densities. 30 and 150 mA) were used as the experimented treatments. All treatments were imposed with a constant voltage gradient of 1 V/cm for 120 hours. Among these treatments. EDTA showed the highest Zn removal efficiency (more than 55%); maximum percent of local In removal along the column reached to 74%. NITRIC ACID and ACETIC ACID produced similar results; mean Zn removal percentage became about 15%. Efficiency of ELECTROKINETIC REMEDIATION increased about 12% and reached to 20% by increasing current density from 30 to 150 mA. Further. the changes in pH along the soil columns after the experiment run (120 hours). showed an increasing trend from anode to cathode.
