“…The first field‐scale application of electrochemical remediation for soils was pioneered commercially by Reinout Lageman, Wiebe Pool and Geert Seffinga of Geokinetics during the late 1980s . They patented the used of circulating electrolytes and ion‐permeable wells to hold the anolyte and catholyte .…”

Electrodialytic remediation has been widely applied to the recovery of different contaminants from numerous solid matrices, solving emerging issues of environmental concern. Results and conclusions reported in studies about real contaminated matrices are summarized in this work. The influence of pH value on the treatment effectiveness has been widely proved, highlighting the phenomenon of ‘water splitting’ in the membrane surface. This dissociation of water molecules is related to the ‘limiting current’ which it is desirable to exceed at the anion exchange membrane in order to produce the entering of protons toward the solid matrix. Other important parameters for the optimization of the technique, such as the current density and the liquid/solid ratio, are also discussed through the revision of studies using real solid matrices. This work also focuses on the pioneer proposal of electrokinetic technologies for the recycling of lithium ion batteries, considering the relevance of waste properties in the design and optimization of the technique. From a thorough literature revision, it could be concluded that further experimental results are needed to allow an optimal application of the technique to the rising problem of residues from batteries. The main aim of this work is to take the first steps in the recovery of valuable metals such as Li and Co from spent batteries, incorporating principles of green chemistry. © 2019 Society of Chemical Industry

“…The electrokinetic remediation approach has seen successful large-scale demonstrations and field tests during the past 10 years in North America and Europe [146,147]. It has been shown to be applicable to removal of a wide range of soil toxins including Cr, Pb, Hg, Ni, Cl − , CN − , phenol, benzene, toluene, and so on.…”

“…The most important applications on soil treatment, which can be called electroremediation, began nearly 15 years ago in research laboratories in the Netherlands 5 , and in the USA 6,7 , almost at the same time. Electrokinetic processes, which can be used in situ 8 , are able to treat ionic pollutants such as heavy metals 9 , or other cationic species like arsenic 10 and anionic species like uorine 11 , but also some ionic or soluble hydrocarbons like phenol 12,13 .…”

E lectrokinetic phenomena can be employed for a soil decontamination process generally called electroremediation. The ionic species in solution migrate through a porous medium essentially by electro-osmosis and electromigration. The aim of this work was to contribute to knowledge of this process by studying the effect of some operating conditions on the species recovery through an experimental program. The in uence of the electrical eld applied to the medium and the initial concentration of the soil solution, in particular, are studied. First, the electrokinetic transport phenomena are presented. Then, the experimental setup and procedures carried out are described. The setup consists of a speci c electroremediation cell containing a Na-doped kaolinite medium. Chemical reactions were limited by using the sodium as a tracer. The experimental results show the important coupling existing between solution concentration and the electrical current and their in uence on both the amount and the rate of transported mass. Moreover, the dependence of the electro-osmotic coef cient on the electrical eld applied was demonstrated. The in uence of the solution concentration on the electro-osmosis is not obvious, probably due to the light modi cation of the zeta potential for the system studied.
