ELECTROCHEMICAL SYSTEM AND METHOD FOR REMOVAL OF CHARGED CHEMICAL SPECIES FROM CONTAMINATED LIQUID AND SOLID WASTE

摘要

PROBLEM TO BE SOLVED: To provide an electrokinetic system which can remove charged chemical species from a sample. SOLUTION: The electrokinetic system comprises an anode compartment, a cathode compartment, a treatment zone (including a sample container and a chamber) which has been connected so that a fluid flows between the anode compartment and the cathode compartment, means for applying a voltage gradient across the anode compartment and the cathode compartment, and a pH controller. The chamber is provided between the anode compartment and the sample container and between the cathode compartment and the sample container. The chamber contains a porous matrix material for hindering the movement of a charged contaminant component and allowing charged chemical species to pass therethrough. Charged chemical species contained in the sample are moved due to the voltage gradient. The pH adjustment of the treatment zone accelerates the accumulation of contaminants in the porous matrix material and accelerates the separation of charged chemical species.
