高效液相色谱-串联质谱法测定塑料建材中的六溴环十二烷

Determination of Hexabromocyclododecane in Plastic Building Materials by High Performance Liquid Chromatography-Tandem Mass Spectrometry

针对塑料建材中商品化三种六溴环十二烷同分异构体建立了检测方法,检测方法回收率均大于98%,相对标准偏差(RSD)≤6.1%。α-HBCD的检出限为0.24 mg/L,β-HBCD为0.58 mg/L,γ-HBCD为0.30 mg/L。采用该方法对市售实际样品进行分析检测,验证了该方法的准确、可靠,对于该行业的规范性监管具有重要的意义。

In this paper, a method for the determination of three commercial hexabromocyclododecane(HBCD) isomers in plastic building materials was established. The recovery of the determination method was more than 98%, and the relative standard deviation(RSD)≤6.1%. The detection limit of α-HBCD was 0.24 mg/L, β-HBCD was 0.58 mg/L, γ-HBCD was0.30 mg/L. The accuracy and reliability of the method are verified by the analysis and detection of the actual samples on the market, which is of great significance for the normative supervision of the industry.
