Electrokinetic remediation of soil polluted with inorganic ionic species

In recent years, the development of suitable technologies for the remediation of environmental contaminations has attracted much attention. Among these, electrochemical approaches have gained a prominent place thanks to the many possible applications and their proven effectiveness. This is particularly evident in the case of inorganic/ionic contaminants, otherwise difficult to treat adequately with conventional methods. The purpose of this chapter is to present the state of the art in the electrokinetic remediation of soils polluted by inorganic ionic compounds. The basis of technology will be briefly mentioned, together with the phenomena that occur in the soil and that allow its effectiveness.
