Resumo(s)
Electrokinetic remediation has been increasingly used in soils and other matrices for numerous contaminants such as inorganic, organic, radionuclides, explosives and their mixtures. Several strategies were
tested to improve this technology effectiveness, namely techniques to solubilize contaminants, control
soil pH and also couple electrokinetics with other remediation technologies. This review focus in the
experimental work carried out in organochlorines soil electroremediation, aiming to systemize useful
information to researchers in this field. It is not possible to clearly state what technique is the best, since
experimental approaches and targeted contaminants are different. Further research is needed in the
application of some of the reviewed techniques. Also a number of technical and environmental issues will
require evaluation for full-scale application. Removal efficiencies reported in real contaminated soils are
much lower than the ones obtained with spiked kaolinite, showing the influence of other factors like
aging of the contamination and adsorption to soil particles, resulting in important challenges when transferring technologies into the field.
