| 摘 要： | 建立一种采用分散液液微萃取-高效液相色谱法(dispersive liquid-liquid microextraction coupled with high performance liquid chromatography, DLLME-HPLC)联用对豆浆中的双酚A进行萃取和检测的新方法, 并考察不同因素对萃取回收率和富集倍数的影响. 实验结果表明, 在最优化的萃取条件下, 在1~100 μg/L质量浓度范围内, 双酚A的质量浓度与色谱峰面积呈良好的线性关系, 检出限为0.3 μg/L, 加标回收率在91.6%~97.5%之间, 相对标准偏差小于6%. 这说明该方法的准确度和重现性较好, 具有可行性, 适用于对市售豆浆饮品中双酚A质量含量的测定.

| 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. |
