| 中文摘要: |
| 采用超高效液相色谱-串联质谱法测定地表水中21种氨基甲酸酯和有机磷农药，通过优化试验条件，使方法在0.500 μg/L～100 μg/L范围内线性良好，方法检出限为0.1 μg/L～6.2 μg/L。对空白水样做3个质量浓度水平的加标回收试验，5次测定结果的RSD为0.3%～9.5%，回收率为82.0%～113%。将该方法用于测定徐州某地表水样品，3个水样均为未检出。 |
| 英文摘要: |
| A method for determination of 21 pesticides in surface water by UPLC MS MS was developed．By optimizing the experimental conditions, good linearity was observed in the range of 0.500 μg/L～100 μg/L and the method detection limit was 0.1 μg/L～6.2 μg/L. The RSDs of spiked samples with 5 repeated measurements in three concentration levels were 0.3%～9.5% and the spiked recoveries were 82.0%～113%. The method was applied to detecting three surface water samples in Xuzhou, and the residues of all these pesticides were undetected. |
