目的 鉴于实验室仪器分析方法不适合现场快速检测食品容器中的双酚A，建立薄层色谱（TLC）方法对样品中双酚 A 进行定性检测。 方法 以 PC 材质桶装水水桶作为样品， 甲醇为提取溶剂 ， 石油醚/乙酸乙酯/乙腈体系（体积比为 7∶3∶0.5）为展开剂 ， 碘蒸汽显色， 检测出食品容器中的双酚A， 并通过红外光谱验证测定结果。 结果 采用 TLC 法能有效地分离检测食品容器中的双酚A。 结论 TLC 法操作简便、灵敏度高、重现性好，适用于食品容器中双酚A的现场快速检测。

Objective To set up a thin layer chromatography (TLC) assay for qualitative determination of bisphenol A in food containers as a field rapid determination method to overcome the disadvantages of laboratory instrumental analysis. Methods Bisphenol A was determined by extracting from polycarbonate (PC) water bottle with methanol, eluting with petroleum ether/ethyl acetate/acetonitrile (volume ratio 7∶3∶0.5) and developing color with iodine steam on TLC plate. And the determination results were further verified by infrared spectroscopy. Results Bisphenol A in food containers was effectively detected by TLC. Conclusion This method is convenient, sensitive and highly reproducible, and is therefore suitable for rapid field determination of bisphenol A in food containers.
