Three hydrophobic ionic liquids (IL) 1-octyl-3-methylimidazole hexafluorophosphate ([OMIM]PF6) (1-butyl-3-methylimidazole hexafluorophosphate ([BMIM]PF6),1-hexyl-3-methyl-imidazole hexafluoro-phosphate ([HMIM]PF6), were coated by Fe3O4@SiO2 nanoparticles with core-shell structure to prepare magnetic solid phase extraction agent (Fe3O4@SiO2@IL) and establish a new method of magnetic solid phase extraction (MSPE) coupled with Fluorescence spectrophotometery for separation/analysis of safranin T (ST). The results showed that safranin T was adsorbed rapidly by Fe3O4@SiO2@[OMIM]PF6 and eluted by ethanol., pre-concentration factor of the proposed method was 20-fold. Under the optimal conditions the linear range, detection limit (DL), correlation coefficient (R) and relative standard deviation (RSD) were found to be 0.30-130.00 μg L-1, 0.05μg L-1, 0.9998 and 0.35% (n=3, c=10.00 μg L-1), respectively. The Fe3O4@SiO2 NPs can be used repeatedly for 10 times. This proposed method has been successfully applied to the determination of safranin T in food samples.
