Prospects on integrated electrokinetic systems for decontamination of soil polluted with organic contaminants

Overall, investigations about the utilization of electrokinetic technology alone or in combination with other processes have attracted particular attention recent years for remediation soils contaminated heavy metals and organic compounds. This fact is due to its peculiar benefits together capability operating a fine low-permeability matrix. review aimed ascertain most developments on commonly proposed integrated technologies (electrokinetic soil washing, electrokinetics coupled permeable reactive barriers, electrokinetic-advanced oxidation processes, bioelectrokinetic remediation), by evaluating gaps, challenges, trends these systems last years. Special paid current approaches overcoming main bottlenecks concerning scale-up reduction electric energy consumption integration renewable energies.
