摘要
微囊藻毒素是有害的蓝藻水华释放的有毒代谢物。建立了有效准确的检测方法，对固相萃取-高效液相色谱测定水中痕量藻毒素的部分实验过程进行了优化处理。流动相体积分数：35％乙腈＋65％水；体积流量：0．8～1．0mL／min；紫外检测波长239nm；进样量10μL；在该争件下，以HPLC测定MC的检测限值为0．1mg／L。应用该法分析了2007年太湖蓝藻爆发期间的水样，结果表明方法具有实用性。
The potent toxin microcystin was frequently released during cyanobacterial blooms in eutrophic waters and made a risk to human health and environment. An efficient and accurate determination method is needed. This manuscript mainly focuses on the determination of Trace Level Microcystions in Water using Solid-phase Extraction and High Performance Liquid Chromatography, and optimizes part of the experiment steps. The detection limite for MC in water system is 0.1 mg/L. This method described here has preferable value in practical application proved by analysis with natural water.
