Figure 1 (A) Effect of different ILs as extraction solvents on drug recovery. (B) Effect of the dispersive solvent on drug recovery (5 mL total sample volume, 100 µL of IL, and 200 µL [BMIM][BF4], mixed by vortexing for 20 s, followed by 5-min centrifugation at 4000 rpm).
Figure 2 Response surfaces for A) oxolinic acid, B) flumequine and C) the desirability function obtained during the optimization procedure.
