Surfactant-enhanced electrokinetic remediation is an emerging technology that can effectively remove hydrocarbons from low-permeability soils. In this study, the electrokinetic remediation using APG(alkyl polyglucoside) was conducted for the removal of phenanthrene from kaolinite. APG, which was an environmentally compatible and non-toxic surfactant, was used at concentrations of 5, 15, and 30g/1 to enhance the solubility of phenanthrene. Also an electrolyte solution was used for considering a relation between electrical potential gradient and removal efficiency of phenanthrene. When the electrolyte solution was used, it represented low electrical potential gradient, but the removal efficiency was lower than that of no electrolyte system. Removal efficiency of phenanthrene in EK process using surfactant solution depended on concentration of surfactant. Because surfactant increased the solubility and the mobility of phenanthrene, when surfactant concentration was high, high removal efficiency was observed.
