摘　　要：采用高效液相色谱法测定发泡聚苯乙烯材料中六溴环十二烷的含量。发泡聚苯乙烯材料样品用乙腈提取,以GL Sciences Inc Inertsil ODS-SP色谱柱（250mm×4.6mm,5μm）为分离柱,以乙腈-水（85＋15）溶液为流动相,在检测波长254nm处进行测定。六溴环十二烷在一定的质量浓度范围内与其峰面积呈线性关系,方法的检出限（3S/N）在140~200mg·kg-1之间。以空白样品为基体进行加标回收试验,所得回收率在88.6%~103%之间,测定值的相对标准偏差（n=7）在1.2%~6.5%之间。HPLC was applied to the determination of hexabromocyclododecane in expanded polystyrene. The sample of expanded polystyrene was extracted with acetonitrile. G-L Sciences Inc Inertsil ODS-SP chromatographic column （250 mm×4. 6 mm, 5μm ） was used as stationary phase, and a mixture of acetonitrile and water （85＋ 15） as mobile phase. UV-detection at 254 nm was adopted in the determination. Linear relationship between values of peak area and mass concentration of the hexabromocyclododecane was kept in definite ranges, with detection limits （3S/N） in the range of 140-200 mg·kg-1. On the base of blank sample, test for recovery was made by standard addition method; values of recovery found were in the range of 88.6%-103%, with RSD＇s （n=7） in the range of
