摘要: 持久性有机污染物十溴二苯醚(BDE-209)作为塑料添加剂之一,对环境和人体健康的影响受到了全球广泛的关注。塑料等复杂基体的前处理过程对于目标化合物的准确定性和定量分析非常关键。以聚乙烯(PE)塑料标准物质中的BDE-209为研究对象,采用超声的方法萃取塑料中的BDE-209,并使用Agilent 1290高效液相色谱(HPLC-DAD)对萃取物中的BDE-209进行了定量分析。通过优化前处理过程,解决了塑料溶解再析出的问题。本方法得到的检测结果准确性高,稳定性良好,RSD小于3.9%。仪器检出限(S/N=3)和定量限(S/N=10)分别为0.017 μg·mL−1和0.05 μg·mL−1,BDE-209的线性范围为0.5 μg·mL−1~50.0 μg·mL−1,R2=0.999,可将其应用到聚丙烯(PP)、丙烯腈-丁二烯-苯乙烯(ABS)等塑料基体标准物质候选物的研制工作中。Abstract: Plastic has become a common material in our daily life. The influence of a plastic additive, decabromodiphenyl ether (BDE-209), on the environment and human health has gradually attracted worldwide attention. The pretreatment of complex matrix such as plastic is very important for accurate qualitative and quantitative analyses of target compounds. In this study, the extraction and analysis of the target BDE-209 in a matrix of polyethylene (PE) plastic Certified Reference Material (CRM) by using Agilent 1290 HPLC-DAD were carried out. By optimizing the pretreatments process, the problem of plastic dissolution and precipitation was solved, and the final sample solution could be detected and analyzed by using Agilent 1290 HPLC-DAD. Good accuracy and stability of the detection results were obtained. RSD was less than 3.9%. The LOD (S/N=3) and LOQ (S/N=10) of decabromodiphenyl ether were 0.017 μg·mL−1 and 0.05 μg·mL−1, respectively. The linear range of BDE-209 was 0.5 μg·mL−1~50.0 μg·mL−1 with R2=0.999. The method can be applied to quantitative analysis of CRM candidates such as polypropylene (PP) and acrylonitrile-butadiene-styrene (ABS).
