Preliminary Studies on the Recovery of SVOC from Soil using Pressurized Fluid Extraction with Methanol/Water

Abstract

The analysis of contaminated soil and sludge samples for semi-volatile organic compounds (SVOC) has traditionally been performed using gas chromatography/mass spectrometry (GC/MS) (EPA SW-846, Method 8270). This method relies on the extraction of contaminants from the samples utilizing a variety of organic and chlorinated solvents. This study shows the effective use of a Dionex Accelerated Solvent Extractor 200 (ASE) along with Stir Bar Sorptive Extraction (SBSE) with methanol replacing the undesirable chlorinated solvents.
