ABSTRACT:
A flow-through capacitor and a controlled charge chromatography column system using the capacitor for the purification of a fluid-containing material, which column comprises an inlet for a fluid to be purified and an outlet for the discharge of the purified fluid, and a flow-through capacitor disposed within the column. The flow-through capacitor comprises a plurality of spirally-wound, stacked washer or rods to include a first electrically conductive backing layer, such as of graphite, and a first high surface area conductive layer secured to one side of the backing layer, such as carbon fibers, and a second high surface area conductive layer secured to the opposite side of the backing layer, the high surface area material layers arranged to face each other and separated by a nonconductive, ion-permeable spacer layer to insulate electrically the backing and conductive layer. The system includes a DC power source to charge the respective conductive layers with different polarities whereby a fluid-containing material passing through the column is purified by the electrically conductive, high surface area stationary phase and the retention thereof onto the high surface area layer and permitting, for example, the purification of aqueous solutions of liquids, such as salt, and providing for the recovery of a purified liquid.
