建立了奶瓶中双酚A、烷基酚及烷基酚聚氧乙烯醚残留量的高效液相色谱-荧光测定方法。样品用二氯甲烷-甲醇提取后，采用高效液相色谱分离，荧光检测器检测。BPA、OP、NP、OPEO在0.05~1.0 µg/mL，NPEO在0.2~1.0 µg/mL范围呈线性。对奶瓶样品作添加回收试验，各种成分的平均回收率在81.1%~100.3%之间，相对标准偏差在2.7%~5.5%之间。方法检出限：BPA为1 mg/kg；OP、NP、OPEO为2 mg/kg；NPEO为5 mg/kg。结果表明，该法简便、灵敏、精确度高，适用于奶瓶中双酚A、烷基酚及烷基酚聚氧乙烯醚的残留分析。

A method was developed for the determination of biphenol A, alkylpheniols and alkylphenol ethoxylates residues in nursing bottle by HPLC-RF. Samples were extracted by dichloromethane- methanol, and analyzed by HPLC-RF. The linear range of BPA, OP, NP, OPEO were within 0.05~1.0 µg/mL and that of NPEO was within 0.2~1.0 µg/mL. Recovery rates of these compounds in nursing bottle ranged from 81.1% to 100.3%, and the relative standard deviations were of 2.7%~5.5%. The detection limits of the method was: BPA 1 mg/kg, OP 2 mg/kg, NP 2 mg/kg, OPEO 2 mg/kg, and NPEO 5 mg/kg. This method was simple, sensitive and precise, which was suitable for qualitative and quantitative analysis of BPA、AP and APEO residues in nursing bottle.
