Abstract: Electrokinetic remediation is an environment-friendly and highly efficient in-situ technique. In recent years，electrokinetic remediation technique has been developed rapidly in China and abroad. In order to enhance the removal rate of pollutants，using chemical regents to enhance the electrokinetic remediation process has been a research focus in this area. In this paper，the basic principle，process characteristics and current challenges for electrokinetic remediation are introduced. The research of different kinds of chemical enhancers，together with the recent progress，application in practice and future trends are presented.
