Determination of methoxypolybrominated diphenyl ethers in the coastal marine environment using solid-phase extraction and gas chromatography coupled with negative chemical ionization mass spectrometry(固相萃取净化-气相色谱-负化学源质谱法测定近岸海洋环境中的甲氧基多溴联苯醚)
甲氧基多溴联苯醚（methoxypolybrominated diphenyl ethers，MeO-PBDEs）广泛存在于生物体和海洋环境。以象山海域的生物体和沉积物为样本，采用固相萃取净化-气相色谱-负化学源质谱法，检测了6种MeO-PBDEs，结果显示，当目标分析物浓度为0.1~20.0 μg∙L−1时，线性关系良好（R2> 0.999），检出限为0.13~0.22 μg∙kg−1，定量限为0.42~0.72 μg∙kg−1，实际样品的平均回收率为71.2%~116.2%。MeO-PBDEs的分布状况调查结果显示，藻类样品中仅检出6-MeO-BDE-47，且浓度较低，其他生物体中检...
