摘　　要：饮用水源水样品经过直接进样或固相微萃取法净化后,用超高效液相色谱/串联质谱测定水中11种藻毒素。通过试验优化测定条件,使该方法在0.500μg/L^50.0μg/L范围内线性良好,检出限为0.01μg/L^0.05μg/L。对同一实际环境样品做3个质量浓度水平加标回收试验,6次测定结果的RSD为2.2%~9.3%,回收率为76.1%~108%。将该方法用于测定环巢湖湖面12个监测断面水样,结果 3组样品中MC-YR、MC-LR和MC-RR值为0.3μg/L^0.8μg/L。The samples from the drinking water source were directly injected or pretreated by solid phase microextraction,11 kinds of algal toxins were determined by ultra high performance liquid chromatography/tandem mass spectrometry.Under the optimized detection conditions,the linear range was 0.500μg/L^50.0μg/L and the detection limits were 0.01μg/L^0.05μg/L.Three concentration levels of spiked recovery tests were carried out on the same practical sample,the RSD of 6 duplicate measurements were 2.2%~9.3%and the recoveries ranged from 76.1%to 108%.This method was applied for monitoring 12 sections in Chaohu lake,the results showed MC-YR、MC-LR and MC-RR were 0.3μg/L^0.8μg/L.
