摘　　要：采用ASE-300快速溶剂取萃仪提取样品中全氟辛烷磺酰基化合物(PFOS),经浓缩、净化、过膜、定容后,用液相色谱串连质谱法测定,外标法定量。采用选择离子检测进行阳性确证,提出了纸制品中PFOS的检测方法。本方法的最低检出限、线性范围和方法回收率分别为:0.10mg/kg、0.10～10.0mg/kg和71.0%～103.0%。The PFOS in paper products was extracted with methanol by the accelerated solvent extractor ASE-300. Then, the extracted liquid was concentrated, purified, film-filtered and volume-specified. It was determined by LC-MS/MS, the amount was determined by external method. By using selective ion monitoring for positive evidence, the determina- tion method for PFOS in paper products by LC-MS/MS was developed. The results showed that detection limit, linear range, and recovery rate of this method, for perfluorooctane sulfonates （PFOS）, are 0.10 mg/kg, 0.10-10.0 mg/kg and 71.0%-103.0% respectively.
