The U.S. EPA conducted a study to evaluate the Soxtec extraction of 29 target compounds from spiked sandy clay loam and clay loam. The study also compared two solvent mixtures and methylene chloride-acetone and investigated the effect on method recovery of five factors (matrix type, spike level, anhydrous sodium sulfate addition, total extraction time, and immersion/extraction time ratio), their two way interactions, and a three-way interactioin (matrix X spike X time). Limited experimental work was performed with 64 basic/neutral/acidic compounds spiked into clay loam and with standard reference materials certified for polynuclear aromatic hydrocarbons.
