摘要：

Ultrasonic extraction technique was used to extract perflurooctanoic acid (PFOA) and its salts from fluro-paints.The extract was quantified after filtration and concentration by gas chromatography-mass (GC-MS) method using perflurodecanoic acid methyl ester as an internal standard.The GC-MS conditions were: HP-Innowax capillary column; oven temperature,50℃(5 min)30℃/min240℃(5 min); splittless mode; injection volume,1μL; negative chemical ion source,reacting gas,CH4,20%; select ion scan mode (SIM);Line range was 1.0-1.0×105 μg/L; the correlation coefficient was 0.999; the low limit of detection (LOD) was 0.1 μg/L.The RSD was 4.24% and 3.58% respectively for low and high concentration of PFOA,and the average recovery was between 86%-111%.
