Fundamental of Reactive and Thermal Processes in Electrochemically Assisted Soil Remediation

  • Chapter
  • First Online:
Electrochemically Assisted Remediation of Contaminated Soils

Part of the book series: Environmental Pollution ((EPOL,volume 30))

Abstract

Electrokinetic soil remediation involves different processes that allow the transport of pollutants in the soil: electromigration, electrophoresis, and electroosmosis. Furthermore, the application of an electric potential to the electrodes inserted in the soil also leads to other reactive and thermal processes: electrolysis and electrical heating. These last ones significantly influence the removal of pollutants retained in the soil, promoting several chemical and physical changes in the soil during remediation. Based on the advantages of these processes, novel treatment technologies combined with electrokinetic remediation have been developed for the removal of several pollutants. In this chapter, the fundamentals of electrolysis and electrical heating are described, in addition to the integration of different reactive and thermal processes with electrokinetic remediation.
