Abstract
A method for remediating contaminated soil includes adding a heat-activated oxidizing agent into the soil; exposing the soil to direct current through a first set of electrodes so as to cause migration of the oxidizing agent through the soil and pore water contained in the soil; and exposing the soil to alternating current through a second set of electrodes so as to heat the soil and thus to activate the oxidizing agent. The first and second sets of electrodes are optionally the same set.
Claims18
A method for the remediation of contaminated soil comprising:
- adding a heat-activated oxidizing agent into the soil, such soil including pore water;
- exposing the soil to direct current through a first set of electrodes so as to cause migration of the oxidizing agent through the soil and pore water;
- and
- exposing the soil to alternating current through a second set of electrodes so as to heat the soil and thus to activate the oxidizing agent.
