摘要
建立了XAD-2树脂富集-高效液相色谱(HPLC)检测淡水水体中痕量微囊藻毒素(MCs)的方法。通过对样品前处理中MCs的富集、洗脱等关键环节的单因素考察,确立的树脂富集方法能够高效稳定地将淡水水体中的MCs浓缩富集6000倍,MC-LR和MC-RR的回收率均达到90%以上,效果良好。
A method for determination of microcystins in freshwater by XAD-2 resin concentration-HPLC was established. Single factor comparisons were carried out in such key concentrated processes as elution and concentration in sample preparation. MCs in water sample could be condensed 6000 times by this method. The results showed that this would be an effective method with more than 90% recoveries of MC-LR and MC-RR.
