In this work, the treatment of heavy metals and phenol in the contaminated soil was investigated by applying direct current (DC) and pulse voltage. When the DC was used, the removal efficiencies for Cu, Zn, As, and Pb were 73, 88, 10, and 10%, respectively, and more than 95% for phenol was removed. Furthermore, when a pulse voltage was employed the removal efficiencies for Cu, Zn, As, and Pb were 88, 92, 40, and 40%, respectively, and 87% of phenol was removed. The results indicate that the application of a pulse voltage for the treatment of contaminated soil reduced electro-osmosis, but increased the rate of electric current movement of heavy metals. In addition, the removal efficiencies for As and Pb have been improved due to the enhanced adsorption capacity of clay components in the soil. Therefore, these experimental results could be effectively applied in remediation technology for the treatment of various heavy metals and phenol.
