建立了固相萃取-超高压液相色谱-三重四极杆质谱同时测定水中14种短链和长链全氟化合物(PFCs)的方法.水样经WAX混合型固相萃取小柱富集和净化后,采用BEH C18色谱柱、甲醇和5 mmol/L乙酸铵水溶液作为流动相进行梯度洗脱,质谱采用多反应监测模式,内标法定量分析.14种PFCs在0.1～50 μg/L范围内线性关系良好,相关系数大于0.99,方法检出限和定量限分别为0.09～1.15 ng/L和0.29～3.85 ng/L.在2、10和20 ng/L加标水平下,8种PFCs的平均回收率为85.0％、120.2％和117.4％,平均相对标准偏差为9.2％、9.0％和6.6％,6种PFCs的回收率相对较低,主要由于其在瓶/管壁上的吸附作用导致.应用本方法分析某淡水湖水样,检出4种短链和5种长链PFCs,质量浓度为41.29～49.05 ng/L和98.43～111.02 ng/L.结果表明该方法适用于对环境水体中短链和长链PFCs的同时分析测定.
