Organic Pollutant Extraction Method Comparison

January 5, 2009

Researchers from the University of the Basque Country (Bilbao, Spain) have compared two extraction techniques as preparation methods for analyzing organic pollutants polycyclic aromatic hydrocarbons, polychlorinated biphenyls, phthalate esters, nonylphenols, polybrominated biphenyls, and polybrominated diphenyl ethers in water samples.

Researchers from the University of the Basque Country (Bilbao, Spain) have compared two extraction techniques as preparation methods for analyzing organic pollutants polycyclic aromatic hydrocarbons, polychlorinated biphenyls, phthalate esters, nonylphenols, polybrominated biphenyls, and polybrominated diphenyl ethers in water samples. The analyses consisted of stir-bar sorptive extraction coupled with thermal desorption gas chromatography–mass spectrometry (GC–MS) and membrane-assisted solvent extraction coupled with large volume injection-programmed temperature vaporization GC–MS. They examined variables such as extraction solvent, extraction time, sample volume, and desorption parameters, and found that both procedures produced similar results.
