固相萃取高效液相色谱法测定水中痕量-微囊藻毒素

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索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。

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
