A rapid and sensitive method was developed for the analysis of 6 polybrominated biphenyl ethers(PBDEs) at trace levels in environmental water samples by gas chromatography-tandem mass spectrometry(GC-MS/MS) with a synthesized zeolite imidazolate framework-8(ZIF-8) as solid phase microextraction coating.The experimental conditions were optimized with single factor tests,and the optimal conditions were as follows:extraction time:50 min,extraction temperature:50 ℃,pH value:70,desorption temperature:280 ℃,desorption time:5 min,and without salt addition.Under the optimized conditions,the calibration curves for 6 PBDEs were linear in the range of 1-1 000 ng/L with limits of detection and limits of quantitation of 008-229 ng/L and 023-732 ng/L,respectively.The intra day and inter day RSDs were in the range of 43%-65% and 69%-93%,respectively.This method was successfully applied in the analysis of PBDEs in 4 environmental water samples(tap water,spring water,pond water and landfill waste water) with recoveries of 816%-109%.
