Abstract

The electrokinetic process is an innovative technology that shows much promise for the remediation of contaminated soil and groundwater. The pH can significantly affect the migration of contaminants. It was easier to remove the weak organic acids such as chlorophenols at higher pH value. However, partial degradation of chlorophenol occurred close to the electrodes. The contaminated soil can be remediated by the combination of the electrokinetic process and electrochemical reaction. After 140 min of treatment, the removal efficiencies of four phenol and chlorophenols could reach 85% at voltage 1200 V m-1, current 10 mA and pH = 9.8.
