摘    要: 利用OASIS HLB固相萃取柱富集和净化样品,采用高效液相色谱分离,紫外及荧光检测,建立了不同饮料基质中的壬基酚(NP)、辛基酚(OP)和双酚A(BPA)等类雌激素的测定方法,并用该方法对市售部分产品进行了测定。不同加标水平的BPA,NP和OP的回收率为91.08%~103.19%,其相对标准偏差为0.5%~5.49%。该方法具有操作简单、灵敏度高和重现性好等优点。

关 键 词:固相萃取  高效液相色谱法  壬基酚  辛基酚  双酚A  饮料

Abstract:A comprehensive analytical method based on high performance liquid chromatography-ultravioiet-fluorescence detection (HPLC-UV-FL) has been established for the determination of bisphenol A (BPA), nonylphenol (NP) and octylphenol (OP) in beverages with different samples and concentrations. Clean-up of samples was performed on an OASIS HLB solid extraction cartridges (6 mL, 200 mg). The method was successfully applied to the investigation of residual bisphenol A, nonylphenol and octylphenol in the beverages (mineral waters and soft drinks) available in commercial markets in Beijing. Recoveries for bisphenol A, nonylphenol and octylphenol at different spiked levels were ranged from 91.08% to 103.19% with relative standard deviations of 0.5% to 5.49%. The method is simple with good reproducibility and (selectivity,) and high sensitivity.
Keywords:solid phase extraction  high performance liquid chromatography  nonylphenol  (octylphenol  ) bisphenol A  beverages
