| 中文摘要: |
| 采用超高效液相色谱-串联质谱法直接进样测定地表水中26种有机污染物，通过优化试验条件，使各目标化合物在100 μg/L~100 μg/L范围内线性良好，相关系数(r2)＞0995，方法检出限为0003 μg/L~10 μg/L。将该方法用于地表水样的测定，加标回收率为790%~120%，6次测定结果的RSD均＜15%。 |
| 英文摘要: |
| By optimizing the conditions of chromatography， mass spectrometry and filtration membrane selection， a method of determining 26 organic pollutants in surface water by ultra high performance liquid chromatography mass spectrometry with direct injection was established. The target compounds had a good linear relationship in the range of 1.00 μg/L to 100 μg/L， the correlation coefficient （r2） was over 0.995. The detection limits ranged from 0.003 μg/L to 1.0 μg/L. When applying this method in surface water determination， the recoveries were from 79.0% to 120%， the relative standard deviation of the samples by 6 times duplicated measurement were all less than 15%. |
