Electrokinetic decontamination of soils polluted by heavy metals and polycyclic aromatic hydrocarbons.
In lab.-scale studies, heavy metals (Cd) and polycyclic arom. hydrocarbons (phenanthrene) were >90% removed from soil by electroosmosis. The cation-exchange resin placed at the cathode could be regenerated and recycled to the process. The duration of the treatment was comparable to those of the microbiol. treatments.
