Abstract:

A novel method was developed for determination of bisphenol A in soybean milk using dispersive liquid-liquid microextraction coupled with high performance liquid chromatography (DLLME-HPLC). Under the optimal conditions, the peak area had a linear relation with the concentration of bisphenol A over the range of 1~100 μg/L. The detection limit was 0.3 μg/L and recovery was among 91.6%~97.5%. The method had good accuracy and reproducibility, and was appropriate for determination of bisphenol A in soybean milk.
