摘要：十溴联苯醚（decabromodiphenyl ether，DecaBDE）是一类新型持久性有机污染物（Persistent Organic Pollutants，POPs），已引发环境污染，危害生物和人类健康，但目前仍未建立一种稳定可靠的检测方法。通过优化气相色谱质谱仪的进样口温度、离子源温度等仪器工作条件，对比不同提取条件、提取剂、提取时间，从而确定了十溴联苯醚的最佳分析条件。结果发现，以甲苯为提取溶剂，采用索氏抽提法提取沉积物和污泥样品中的十溴联苯醚，连续提取24h，效果最佳。方法回收率为78．54％～98．42％，检测限为0．1mg·L^-1。
Decabromodiphenyl ether（DecaBDE ） is a new kind of persistent organic pollutants and has been a potential environmental hazard to biological diversity and human heahh. However, there hasnJt been any effective and reliable method for the analysis of DecaBDE in sediment and sludge. To establish an optimum method for DecaBDE detection in sediment and sludge samples, the injector temperature and ion source temperature of Gas Chromatography Mass Spectrometer （GC/MS）, as well as the efficient extraction agent, time and other extraction conditions were determined in this study. The optimum extraction and determination condition for sediment and sludge samples containing DecaBDE was developed with toluene as the extract solvent for 24 h extraction time by a Soxhlet system. It was found that the recovery ratio of DecaBDE ranged from 78.54% to 98.42% and the detection limit was 0.1 mg·L^-1.
