Abstract
The invention provides an apparatus for electrokinetic transport through soil, comprising an electrode and a containment surrounding the electrode, the containment comprising a layer of a porous material and a rigid porous member disposed between the electrode and the porous material to support or secure the first material. The porous material and rigid porous member allow passage of water, hydrogen ions, hydroxyl ions and one or more target ions. A preferred porous material is clay or ceramic and a preferred rigid porous member is a perforated plastic tube.
Claims6
An apparatus for electrokinetic transport through soil, comprising:
- (a) an electrode;
- (b) a containment surrounding the electrode, the containment comprising a layer of a first porous material having an electroosmotic permeability coefficient greater than about 10−6 and a hydraulic permeability coefficient less than about 10−3 and a rigid porous member disposed between the electrode and the first porous material to secure the first porous material, wherein the first porous material and the rigid porous member allow passage of water, hydrogen ions, hydroxyl ions and one or more target ions;
- and
- (c) a voltage probe positioned inside the rigid porous member and a voltage probe positioned outside the first porous material to measure the voltage drop across the containment.
