Electrokinetic Remediation - Applicability of Electrokinetic Remediation


Applicability of Electrokinetic Remediation

Electrokinetic Remediation can be implemented for the remediation of soils, sediments and any porous material. This technique is used on both saturated and unsaturated soils though it works better on saturated soils. It can also be implemented on heterogeneous soils and used to treat a wide range of contaminants (Acar et al., 1995). The method is very effective in removal of strontium and cesium from high water content soil (Jane E. Apatoczky, 1992). pH control at the electrodes and the use of enhancement agents would broaden the range of contaminants that can be treated with this process such as lead, mercury and cobalt (Kornilovich et al., 2005). Thus, Electrokinetic remediation is a developing technology which intends to separate and extract radionuclides, heavy metals and organic contaminants from saturated or unsaturated soils, sludges, sediments and groundwater.
