Solid-phase microextraction coupled to gas chromatography/mass spectrometry for determining polycyclic aromatic hydrocarbon-micelle partition coefficients.
Solid-phase microextraction (SPME) coupled to gas chromatography with MS detection has been employed to study the partition coefficients of PAHs to ionic and nonionic micelles. The results obtained in this work for seven PAHs, using 85-microm polyacrylate- and 100-microm poly(dimethylsiloxane)-coated fibers and anionic (sodium dodecyl sulfate), cationic (cetyltrimethylammonium bromide), and nonionic (polyoxyethylene-10-lauryl ether) surfactants, indicate that SPME is a viable method for estimating the partition coefficients of PAHs to micelle. The procedure could also be potentially extended to the measurement of partition coefficients between a wide variety of semi- or nonvolatile compounds and micellar media.
