摘要
Abstract
A method was developed for the determination of 39 polybrominated diphenyl ethers(PBDEs) from mono- to hepta-brominated in coastal sediment by gas chromatography/mass spectrometry. The sample was extracted with a solution of dichloromethane: n-hexane( 1:1,V/V) ,followed by ultrasonic extraction for 60 min at 25℃. The clean-up step was optimized using silica gel and alumina. The detection limit of the method was in the range of 0.003 - 0.10μg/kg. The results indicate that the average recovery of the internal standard was from 66.2% to 118. 6%. The relative standard deviation RSD( % ) was from 0. 8 % to 18. 2%. The method for the detection of 39 PBDE congeners in coastal sediment was sensitive,high reproducible with satisfactory recoveries.关键词
