| 中文摘要: |
| 采用固相萃取处理水样，超高效液相色谱-四极杆-飞行时间质谱法（UPLC-QTOF-MS）测定水样中14种全氟有机酸。通过优化试验条件，使方法在100 μg/L～100 μg/L范围内线性良好，方法检出限为087 μg/L～480 μg/L。空白水样的加标回收率为808%～113%，测定结果的RSD≤37%。将该方法用于测定厦门市某大学周边水样，结果14种全氟有机酸均为未检出。 |
| 英文摘要: |
| 14 kinds of perfluorinated acids(PFAs) in water were detected by solid phase extraction and ultra performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC QTOF MS). With the optimized test conditions, the method had good linearity in the ranger of 1.00 μg/L to 100 μg/L. The detection limits were 0.87 μg/L~4.80 μg/L. The recoveries of blank samples ranged from 80.8% to 113%, the RSDs were below 3.7%. The method was applied to detect surface water samples from around a university in Xiamen, all of the 14 PFAs were not detected. |
