| 中文摘要: |
| 将1-丁基-3-甲基咪唑六氟磷酸离子液体固定于无纺布上形成支撑离子液体膜，结合液相微萃取技术对水样中的有机氯农药进行分离与富集，并用气相色谱法测定。通过试验对影响萃取效率的有关条件进行优化，使该方法在0.500μg/L~10.0μg/L范围内线性良好。方法检出限为0.02μg/L~0.08μg/L，测定0.04μg/L的混合标准溶液平均回收率为75.0%~87.3%，RSD<7%。 |
| 英文摘要: |
| Supported ionic liquid membrane was prepared by fixing 1 butyl 3 methylimidazolium hexafluorophosphate ionic liquid on the non woven fabrics, and was used to separate and enrich organo chlorine pesticides (OCPs) couple with liquid microextraction. And then the enriched OCPs were analyzed using gas chromatography. The conditions of liquid microextraction were optimized by using experiments. This method showed good linear ranges between 0.500μg/L and 10.0μg/L. The determination limits of this method lied between 0.02μg/L and 0.08μg/L. The recoveries of eight OCPs in actual sample lied between 75.0% and 87.3%, and relative standard deviation (RSD) was less than 7%. |
