Description:
Electrokinetic remediation of metal contaminated soils is a promising in-situ soil remediation technology. In electrokinetic soil remediation, a current is applied to two electrodes buried in the soil and the ionic contaminants move towards the electrodes for subsequent cleanup of the localized contaminant. However, implementation of electrokinetic soil remediation is prohibited by:
- buildup of a pH front, leading to increased power consumption and
precipitation of a dispersed and nonrecoverable metal hydroxide, and
- slow transport of metal contaminants.
