DETERMINATION OF DECABROMOBIPHENYL ETHER IN WATER AND SEDIMENT SAMPLES BY GAS-CHROMATOGRAPHY WITH ELECTRON-CAPTURE DETECTION

Traces of decabromobiphenyl ether (DBBE) in water and sediment were de termined by capillary gas chromatography with electron capture detecti on. Rapid sample preparation techniques such as disk-type C-18 solid-p hase extraction and cartridge-type Florisil extraction were used to cl ean 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, respective ly. Average recoveries of DBBE added to river water, sea water, and se diment 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.
