Progress on Electrokinetic Remediation and Its Combined Methods for POPs from Contaminated Soils
电动力学及其联用技术降解污染土壤中持久性有机污染物的研究进展

Electrokinetic remediation (EK) and its combined methods are emerging technologies to remove POPs from contaminated soils in situ in last decade. This paper reviews the five major kinds of electrokinetic remediation methods for POPs from contaminated soils: (1) Classic electrokinetic method; (2) Electrokinetic-Fenton method; (3) Electrokinetic remediation combining with bioremediation method; (4) Electrokinetic remediation combining with surfactants/cosolvents method; (5) Electrokinetic remediation combining with ultrasonic method. The basic principle, characteristics, application areas and research developments of those five methods are discussed respectively. The future development direction of EK remediation for POPs from contaminated soils is anticipated.
