摘要: 提出一种新的离子液体均匀提取方法, 即向水样中加入可溶于水的离子液体 1-己基-3-甲基咪唑四氟硼酸盐([C6Mim][BF4]), 再加入过量六氟磷酸铵(NH4PF6), 形成不溶于水的离子液体1-己基-3-甲基咪唑六氟磷酸盐([C6Mim][PF6]), 水样中的氟罗沙星和磺胺喹噁啉被提取到[C6Mim][PF6]相, 离心分离后, 离子液体可直接用于HPLC分析. 本法测得的氟罗沙星和磺胺喹噁啉的检出限分别为1.8和1.1 μg/L.

关键词: 离子液体, 均匀液相微提取, 高效液相色谱

Abstract: The homogeneous liquid microextraction was developed for extracting fleroxacin and sulfaquinoxaline from water samples. A room temperature ionic liquid [C6MIm][BF4], which is dissolvable in water, and NH4PF6, can be sequentially added into the water samples. The resulting [C6MIm] [PF6], which is not dissolvable in water, can be dispersed in the sample solution as very fine drops. After extraction, phase separation was performed by centrifugation. The sedimented phase was taken with a high performance liquid chromatography(HPLC) microsyringe and injected into the HPLC system for analysis. The detection limits for fleroxacin and sulfaquinoxaline were found to be 1.8 and 1.1 μg/L, respectively.
