| 中文摘要: |
| 采用吹扫捕集-气相色谱/质谱联用法测定水中的丙烯醛和丙烯腈，方法在5.00 μg/L~200 μg/L范围内线性良好，方法检出限分别为4.9 μg/L和0.3 μg/L。用该方法测定3个质量浓度水平的空白加标样，7次测定结果的RSD为 2.8%~6.7%，加标回收率为90.4%~98.3%。用该方法测定某水库和某河流的地表水，丙烯醛和丙烯腈均未检出。 |
| 英文摘要: |
| Purge and trap gas chromatography mass spectrometry was applied to determine acrolein and acrylonitrile simultaneously in water. The method had good linearity from 5.00 μg/L to 200 μg/L. The method detection limits were 4.9 μg/L and 0.3 μg/L. The spiked recoveries in blank water ranged from 90.4% to 98.3%，with the RSDs 2.8%～6.7%．Acrolein and acrylonitrile in some rivers and reservoirs were undetected by this method. |
