微波辅助萃取-气相色谱法同时测定纺织品中6种禁用有机磷阻燃剂

Simultaneous determination of six banned organophosphorous flame retardants in textiles by gas chromatography combined with microwave-assisted extraction

以丙酮为萃取溶剂,采用微波辅助萃取技术对纺织品中的禁用有机磷阻燃剂进行萃取,萃取液采用气相色谱-火焰光度检测器(GC-FPD)测定,从而建立了一种微波辅助萃取/GC-PFD分析方法,同时对纺织品中6种禁用有机磷阻燃剂进行了快速测定。检出限均低于3.0μg/L,加标回收率为81.5%～96.7%,相对标准偏差为3.3%～6.6%。应用该方法对市售的阻燃纺织品中禁用有机磷阻燃剂含量进行了测定,结果发现部分阻燃纺织品中检出高含量的禁用有机磷阻燃剂。

An effective method was established for the simultaneous determination of six kinds of banned organophosphorous flame retardants in textiles.Organophosphorous flame retardants in textiles were first microwave-assisted extracted using acetone as the extraction solvent,and then were analyzed by gas chromatography coupled with flame photometric detector（FPD）.The detection limits of six analytes were all lower than 3.0 μg/L.The spiked mean recoveries varied from 81.5 % to 96.7 % with the relative standard deviations of 3.3 % to 6.6 %.The mehtod developed was simple,rapid and sensitive.The proposed method was successfully applied to the determination of organophosphorous flame retardants in commercially available textiles and the results showed that banned organophospohrous flame retardants of high content existed in some commercial flame retardant textiles.
