Abstract : Soils contaminated with toluene and p-xylene are readily decontaminated at low temperature without combustion when heated with microwave energy under vacuum conditions. Findings indicated that the solvent removal rate was increased several times if the soil samples contain moisture in the form of 3.00 wt.% water. The combination of moisture and vacuum yielded the best results. This observation can be attributed to the enhancement of microwave absorption by the water molecule and by partial pressure effects of the water vapor which is generated upon heating.
