Abstract
Applying a desorbing wave energy to a soil matrix can effect desorption of ionic species which are associated with the matrix. This method is especially applicable to decontamination of soils to which metals and/or radioactive isotopes are adsorbed. The desorbing energy may be microwave energy, sonic or ultrasonic energy, etc., or combinations thereof. An electromagnetic potential also can be applied to the matrix to enhance desorption and or migration of the species. An electrolyte also may be added to the matrix to enhance desorption and or migration of the species.
