Homogeneous Ionic Liquid Microextraction of Fleroxacin and Sulfaquinoxaline from Water Samples

Abstract

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.

Key words: Lonic liquid, Homogeneous liquid microextraction, High performance liquid chromatography(HPLC)
