Trace analysis of perfuorinated alkyl substances in textile goods by LC-MS/MS
A simultaneous trace analysis method was established to determine ten kinds of perfuorinated alkyl substances (PFAS) in textile goods by High-Performance Liquid Chromatography-tandem Mass Spectrometry (HPLC-MS/MS). Samples were extracted by ultrasonication with methanol, and the extract was separated on C18 reversed phase column with methanol-5mmol/Lammonium acetate as the mobile phase. 13C-PFOA and 13C-PFOS was used as internal standards for quantification. The extraction efficiency were compared among three different extraction methods--ion-pair extraction, soxhlet extraction and ultrasonication. The limit of detection, linear range, and recovery range of the method were 0.5ng/g, 0.5ng/g -10ng/g, and 84.6％-111.8％, respectively. Some PFAS, specially PFOS and PFOA, could be found in waterproof, oil proof, and dust proof coating textiles in China.
