Contamination encountered on nuclear sites includes radionuclides as well a range of non-radioactive co-contaminants, often in low-permeability substrates such concretes or clays. However, many commercial remediation techniques are ineffective these substrates. By contrast, electrokinetic (EKR), where an electric current is applied to remove contaminants from the treated media, retains high rem...

The electrokinetic remediation method can function as a primary or secondary technology and be applied in conjunction with other physical biological methods, such soil washing, phytoremediation, bioremediation. Environmental impacts arising from the process determined using life cycle assessment analysis (LCA) tools. This study compared conventional strategy two hybrid strategies: electrokineti...

Abstract—The contamination of significant quantities of soils and sediments with uranium and other actinide elements as a result of nuclear activity poses many environmental risks. The electrokinetic process is one of the most promising remediation techniques for sludge, sediment, and saturated or unsaturated soils contaminated with heavy metals and radionuclides. However, secondary waste is a ...

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...

In recent years, electrokinetic (EK) remediation method has been widely considered to remove metal pollutants from contaminated dredged sediments. Chelating agents are used as electrolyte solutions to increase metal mobility. This study aims to investigate heavy metal (HM) (As, Cd, Cr, Cu, Ni, Pb and Zn) mobility by assessing the effect of different chelating agents (ethylenediaminetetraacetic ...
