In this study, three experiments using the fixed anode technique and approached anode technique were carried out. The first experiment (EK-1) used distilled water as leaching solution (purging solution) at the anode and cathode chamber under voltage gradient was equal to 1.5 V/cm. In the second and third experiments, a solution enhanced with 1M acetic acid (AA) was used as catholic solution. The results indicate that residual concentration of Zn+2 decreases, beginning with an initial value of 850 mg/kg in all portions of soil sample EK-1, EK-2, in addition to EK-3. It seems that the residual concentration of EK-3 (approached anode technique) was lower than that of EK-1 and EK-2 in identical portions.
