| Abstract: | A novel method for the determination of diethylstilbestrol in milk using dispersive liquid-liquid microextraction coupled to high performance liquid chromatography (HPLC) was developed. Important parameters affecting extraction efficiency, such as extraction solvent type and volume, anti-sticking agent type and volume, pH, salt concentration and temperature, were discussed. Under the optimal conditions, the established method had high sensitivity, low detection limit and high stability for the analysis of diethylstilbestrol. Ultrasound-assisted ionic-liquid cold-induced aggregation dispersive liquid-liquid microextraction could be successfully used for the determination of diethylstilbestrol in milk. |
| Keywords: | dispersive liquid-liquid microextraction milk diethylstilbestrol high performance liquid chromatography (HPLC) |
