| 摘 要： | 本文探讨了一种利用毛细管进行液相微萃取的新方法,对萃取剂体积、乳化剂体积、盐溶液浓度等影响因素进行了考察,并用该方法萃取水溶液的苯甲酸并用气相色谱氢火焰离子化检测器(GC-FID)进行检测,以甲苯作为萃取剂,乙醚作为乳化剂,得到校正曲线的线性r2为0.9951,回收率为101.8%,检出限为0.082g/L。

| Abstract: | A new liquid-phase microextraction technique which employs capillary is developed in this dissertation.The benzoic acid water solution was utilized to assess the new liquid-phase microextraction method.After microextraction,the target compounds were separated and determined by the GC-FID.The effects of some extraction parameters such as the volume of solvent,the volume of emulsifier and the salt were studied.The new microextraction method provides a good linearity while toluene and diethyl ether were employed as the extraction solvent and emulsifier,respectively.Studies showed that the r2 for the calibration curve is 0.9954,recovery is 101.8% and LOD is 0.082g/L. |
