ELECTROKINETIC SOIL REMEDIATION

摘要

A process for removing of ions from a contaminated media by applying a DC electric field between at least one anode and one cathode; wherein said process comprises the steps of: providing a treatment cell comprising: an anode chamber; a cathode chamber and a cavity located between the anode chamber and cathode chamber and separated from the two by the presence of a porous material; wherein said anode chamber comprises an anode and said cathode chamber comprises a cathode; placing said media into said cavity; introducing an electrolyte into said cavity filled with media; submerging the anode and the cathode in their respective chambers with electrolyte; applying a DC current to the electrodes causing the contaminant ions present in the media to migrate from the media to the electrolyte within the electrode chamber; removing the electrolyte from the electrode chamber; and optionally, removing the contaminant ions removed from the electrolyte.
