Combination of in-syringe homogenous liquid-liquid extraction and ionic liquid based dispersive liquid-liquid microextraction has been employed for the extraction of aflatoxin B1 from edible vegetable oil samples. Firstly, a homogenous solution of oil sample containing the analyte and acetone (1.5 mL) is formed. Then, this homogenous state was broken by adding 100 µL of deionized water and the analyte was extracted into the produced fine droplets of acetone. In the following, acetone phase was taken and mixed with 65 µL of 1-hexyl-3-methylimidazolium tetrachloroferrate magnetic ionic liquid. The mixture was injected to sodium chloride solution (5 %, w/v) by a glass syringe. The ionic liquid droplets were collected by an external magnet and then, they were used for the determination step by high-performance liquid chromatography equipped with fluorescence detector. Under the optimum conditions, low limit of detection (13 ng kg-1) and quantification (44 ng kg-1), wide...
