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0.006μg/L~50.0μg/L范围内线性良好,方法检出限为0.006μg/L~0.010μg/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%~9.4%。
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 0.006μg/L to 50.0μg/L,the detection limits were 0.006μg/L~0.010μg/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.
