Abstract:
Traces of decabromobiphenyl ether (DBBE) in water and sediment were determined by capillary gas chromatography with electron capture detection. Rapid sample preparation techniques such as disk-type C18 solid-phase extraction and cartridge-type Florisil extraction were used to clean up water and sediment samples, respectively. The detection limits of DBBE were 0.12 ng/mL and 9.7 ng/g in water and sediment, respectively. Average recoveries of DBBE added to river water, sea water, and sediment were 103%, with a relative standard deviation (RSD) of 8.6%; 87%, with an RSD of 10.7%; and 91%, with an RSD of 6.3%, respectively.
