Various extraction techniques have beenexplored for the removal of energetic materials from soil samples.Routine sample clean-up methods prior to analysis include liquidextraction (LE) with sonication [24], centrifugation [17], acceler-ated solvent extraction (ASE), supercritical fluid extraction (SFE)and pressurized fluid extraction (PFE) [3,23,25]. These proceduresare in general time consuming, require an expert operator and con-sequently are more difficult to perform on-site
