| 中文摘要: |
| 为方便地表水中总微囊藻毒素（TMCs）的预警监测，探究提取MC-LR、MC-RR、MC-YR的不同快速前处理方法，建立同时测定3种TMCs的煮沸-过滤-UPLC-MS/MS法。该方法在0.006 μg/L～50.0 μg/L范围内线性良好，方法检出限为0.006 μg/L～0.010 μg/L，实际水样3个质量浓度水平的加标回收率为88.6%～108%，6次测定结果的RSD为2.6%～94%。 |
| 英文摘要: |
| Different rapid pretreatment methods of extracting MC LR、MC RR、MC YR in surface water was studied for the convenience of early warning and detection of total microcystins（TMCs）. A boiling filtration UPLC MS/MS method was developed for simultaneously detecting the 3 TMCs. The method had good linearity in the range of 0.006 μg/L to 50.0 μg/L, the detection limits were 0.006 μg/L～0.010 μg/L. The recoveries of low, medium and high concentration levels were in the range of 88.6%～108%. The relative standard deviations were in the range of 2.6%～9.4%(n=6). This rapid and convenient method could be applied in early warning of large batch of the 3 MCs in eutrophic water. |
