摘    要:微囊藻毒素是有害的蓝藻水华释放的有毒代谢物,对人类及环境具有很大危害性。建立了固相萃取-高效液相色谱测定水中痕量藻毒素的方法。该法对两种常见微囊藻毒素MC-LR、MC-RR的检测限为0.02-0.05μg/L,线性定量范围为0.1-50μg/L。应用该法分析了天然水样,表明方法具有实用性。

关 键 词:微囊藻毒素  固相萃取  高效液相色谱  水污染  痕量分析

Abstract:This paper presents a method for trace level analysis of microcystins in water using solid-phase extraction and high performance liquid chromatography.The optimized condition enabled the determination of common microcystins at levels as low as 0.02~0.05μg/L,and the liner range is from 0.1μg/L to 50 μg/L. The method has been applied to the analysis of field sample from Dianchi lake.
Keywords:Microcystin  solid  phase extraction  high performance liquid chromatography
