Abstract
Electrokinetic remediation is a widespread soil treatment technique especially suited for fine porous matrices. The principle of electrokinetic remediation is based on the application of a low-intensity direct current through the soil between electrodes–cathodes and anodes. This mobilizes charged species, causing ions and water to move towards the electrodes. Metal and positively charged organic compounds move towards the cathode. Anions such as chloride, nitrate, and negatively charged organic compounds move towards the anode. During around 25 years, this principle has been used successfully for the treatment of heavy metal polluted soil. This chapter gives a short overview of the process as an introduction for people not that familiar with the process, and list some tendencies and future directions in the development of the method.
