摘　　要：提出了高效液相色谱法测定电子电气产品中多溴联苯和多溴联苯醚含量的方法。普通塑料样品采用正己烷-丙酮(1+1)混合溶液作为提取溶剂进行微波萃取,含金属的塑料样品采用乙酸乙酯作为提取溶剂进行超声波萃取,提取液采用NUCLEODUR Sphinx RP C18色谱柱为分离柱分离,以不同体积比混合的水和乙腈为流动相进行梯度洗脱,检测波长为226nm。多溴联苯和多溴联苯醚的质量浓度在0.2～50mg.L-1范围内与峰面积呈线性关系,测定下限(10S/N)在2.3～5.0mg.kg-1之间。Contents of polybromo biphenyls （PBB＇s） and polybromo diphenyl ether （PBI）E＇ s） in electronic and electrical products were determined by HPLC. Samples of common plastics were extracted in a micro-wave extractor with a mixture of n-hexane and acetone （1＋1）, and samples of plastics containing metals were extracted ultrasonically with ethyl acetate. The extract was separated on NUCLEODUR Sphinx RP C18 column by gradienl elution with water and acetonitrile mixed solutions of different ratio, and determined at the wavelength of 226 nm. Linear relationships between values of peak area and mass concentration ot PBB＇s and PBI）E＇s were kept in the same range of 0. 2--50 mg·L^-1 with lower limits of determination （10S/N） in the range of 9. 3--5.0 mg ·kg^-1.
