高效液相色谱法测定地表水中微囊藻毒素-LR

应用高效液相色谱法（HPLC）测定地表水中微囊藻毒素-LR（MC—LR）。以乙醇／三氟乙酸混合水溶液为流动相（醇水比例为45：55（V/V），水溶液含0．1％三氟乙酸），MC—LR在ODS色谱柱上获得理想的分离效果；在样品前处理中，使用含0．1％三氟乙酸的乙醇溶液可以获得较好的MC—LR提取效率；通过优化前处理及仪器检测条件，有效去除样品基体干扰，检测结果令人满意。

Determination of Microcystin-LR in Surface Water by HPLC

The microcystin-LR in surface water was determined by HPLC which using ethanol:water(containing 0.1%Trifluoroacetic acid)=45:55(V/V)as the mobile phase.The separation result of MC-LR in the ODS column was satisfied.To get a higher efficiency of extraction in the pre-treatment process,ethanol solution with 0.1%trifluoroacetic acid was used to extract the sample.By optimizing the pre-treatment and conditions of analyze and reducing the affection of interference,we can get a simple,safe and effective result of...
