| 摘 要： | 建立了液液萃取-气相色谱-质谱（LLE -GC/MS）同时测定饮用水中的6种酞酸酯类化合物、百菌清和联苯胺的方法。选用3种有机溶剂进行萃取，筛选出回收率高、操作简单的前处理方法，萃取后经气相色谱-质谱分析。方法表明：8种物质线性良好，相关系数为0．9978～0．9995，用二氯甲烷萃取回收率最佳，回收率在90．1％～118％之间，相对标准偏差在0．24％～7．21％之间。

| Abstract: | A method was developed for the determination of 6 phthalate ester,chlorothalonil and benzidine in drinking water using LLE-GC/MS.The sample was extracted by dichloromethane,n-hexane and cyclohexane,separately.A simple extraction method with high recoveries was chosen.Then the compounds were determined by GC-MS.The result indicated that the calibration curves showed good linear relationship.The correlation coefficients were in the range of 0.997 8 ~0.999 5.Samples extracted with dichlo-romethane showed the highest recovery.The recoveries of 8 compounds were in range of 90.1% ~1 1 8% and the relative standard deviations were 0.24% ~7.21%.The method was suitable for the determination of phthalate ester,chlorothalonil and benzidine in surface water. |
