Ultrasonic method was used to extract PFCs from textiles,and the pretreatment process is convenient.The ten kinds of target compounds,i.e.PFHxA,PFOA,PFNA,PFDA,PFuDA,PFDoA,PFBS,PFHxS,PFOS,and PFDS were separated on C18 reversed phase column in 13 min with step methanol-5 mmoL/L ammonium acetate as the mobile phase.Monitor and qualitative analysis of PFHxA,PFOA,PFNA,PFDA,PFuDA,PFDoA,PFBS,PFHxS,PFOS,PFDS were undertaken at 313.1/268.9,412.9/368.9,462.9/418.9,512.7/468.9,562.7/518.9,612.8/568.9,298.8/99,399.2/99,498.8/99,599/99 respectively.Isotope-labeled internal standard method was used to carry out such tests as the limit of detection,linear range,and recovery range.The results showed they were 0.5μg/m2,0.5-10μg/m2, and 84.6%-111.8%, respectively .It should be pointed out that the limit of detection is 0.μ/m2 by this method which is lower than 1μg/m2 regulated for textiles by EU. This method was accurate and swift,which has been successfully applied to analyze 20 real textile samples.
