Abstract
An optimised method using stir bar sorptive extraction (SBSE) for the determination of nine bromodiphenil ether (Lake Michigan mix) from water samples was developed. Recoveries near to 100% were found by using 20 mm × 0.5 mm (length × film thickness) PDMS commercial stir bars with 100 mL spiked water samples and 20% methanol addition and an extraction period of 25 h.Method sensitivity, linearity, repeatability and reproducibility have been also studied. Detection limits between 0.4 and 9.4 ng/L were calculated for the combination of SBSE and thermal desorption-GC–MS. The procedure was applied a real sample, a surface water contaminated by the effluents, and the results were compared with a classical liquid–liquid extraction method.
