摘要
本文采用不同提取方法以及不同溶剂对煤飞灰环境标准参考物质样品中PAHs的提取效率进行了考察.采用HPLC,毛细管GC以及GC-MS对飞灰样品中的PAHs进行了分析表征,并对前两种分析方法的精密度、准确性和所得结果的一致性进行了研究.
The extraction efficiencies with different solvents and by different methods for polycyclic aromatic hydrocarbons (PAHs) in a coal fly ash environmental standard reference material (SRM) have been investigated. PAHs in fly ash samples have been characterized by HPLC, capillary GC and GC/MS. The precision, accuracy and agreement of analytical data obtained from HPLC and GC have also been studied.
