摘    要:采用气相色谱/负离子化学电离质谱法测定地表水中的硫丹及其代谢物,用正己烷提取,外标法定量。α-硫丹、β-硫丹及硫丹硫酸酯在0.200μg/L~10.0μg/L范围内线性良好,方法检出限分别为0.010μg/L、0.008μg/L及0.010μg/L,空白加标平行测定的RSD为3.9%~4.8%,地表水样品加标回收率为85.5%~93.8%。

关 键 词:α-硫丹  β-硫丹  硫丹硫酸酯  气相色谱/负离子化学电离质谱法  地表水

Abstract:A method for determining endosulfan and its metabolin in surface water was established by using GC/MS with NCI,hexane as extractive solution,quantization by external standard method.Linearties of calibration curve of α-endosulfan,β-endosulfan and endosulfan sulfate were good in range from 0.200 μg/L to 10.0 μg/L,the method detection limits 0.010 μg/L,0.008 μg/L and 0.010 μg/L respectively for the three compounds,RSD of blank and spiked duplicates from 3.9% to 4.8%,spiked recoveries of surface water samples from 85.5% to 93.8%.
Keywords:α-Endosulfan  β-Endosulfan  Endosulfan sulfate  GC/MS with NCI  Surface water
