| 摘 要： | 本研究建立了超声辅助离子液体-分散液液微萃取-高效液相色谱测定环境水样中苯胺(AN)、对氟苯胺(4-FA)、对硝基苯胺(4-NA)、对氯苯胺(4-CA)四种苯胺化合物的方法。以最常用的烷基咪唑六氟磷酸盐类离子液体为萃取剂,通过超声加速萃取剂的分散程度,提高了萃取效率。该方法的检测限达到0.1~73 ng/ml,对黄河水和自来水中的加标回收率均在90.5%~113%之间,回收效果良好。与传统的液液萃取相比,该萃取方法具有绿色、快速、富集效果好、有机溶剂消耗小的优点,可以满足环境水体中苯胺类化合物的测定。

| Abstract: | Ultrasound-assisted ionic liquid dispersive liquid -liquid microextraction combined with high performance liquid chromatography ( HPLC) method for preconcentration and determination of trace amounts of anilines in water samples was es -tablished .1-butyl-3-methylmidazolium hexafluoro -phosphate ( C4 MIM] PF 6 ] ) is selected because it can simultane-ously extract aniline compounds from water .The limits of detection is in the range of 0.1~73 ng/ml.The developed method showed high relative recoveries for Aniline (AN),4-Fluoroaniline (4-FA),4-Nitroaniline (4-NA),4-Chloroaniline (4-CA) at different concentrations from 90.5%to 113%,which ensured the accuracy of method using to detect the amount of anilines in environmental water samples . |
