Electrokinetics in remediation of heavy metal contaminated underground environment

Electrokinetics is an emerging in situ soil remediation technology in foreign countries in recent years. Firstly basic principles of electrokinetics are introduced, and then much attention is paid to several oversea electrokinetic techniques in remediation of heavy metal contaminated soils:Lasagna technology, insertion of a conductive solution between the cathode and the soil, cation-selective membrane, CEHIXM technology, Electro-Klean~(TM) technology, Electrochemical geooxidation, Electrochemical ion exchange, Electrosorb~(TM), pointing out their strengths and drawbacks.Finally the advantages of electrokinetic remediation for heavy metal polluted underground environment are evaluated as a whole and the present problems are put forward.
