| 摘 要： | 采用液相色谱-质谱对塑料食品包装物中11种环境雌激素(雌三醇、双酚A、对壬基酚、对特辛基苯酚、特丁基对苯二酚、苯酚、二丁基甲基酚、己烯雌酚、对苯二酚、邻甲基对苯二酚、17-β-雌二醇)含量进行测定。样品用二氯甲烷溶解、甲醇沉淀后，经C18固相萃取小柱净化，用液相色谱、质谱检测器，对塑料食品包装物中11种环境雌激素的测定可取得满意的结果。该方法样品平均加标回收率为81.40%～111.11%，相对标准偏差为3.9%～9.7%；塑料食品包装物中11种环境雌激素的检出限为0.0075～0.32mg/kg。

| Abstract: | A liquid chromatography and mass spectrometry method for determination of 11 environmental estrogens in food packaging materials was developed. The samples were dissolved by dichloromethane and precipitated by methanol. The filtrates were cleaned up through C18 SPE cartridge, and then separated with liquid chromatography, detected with mass spectrometry. Average recoveries between 81.4% and 111.11% and relative standard deviations between 3.9% and 9.7% were obtained for spiked samples. The detection limits of 11 environmental estrogens were between 0.0075 mg/kg and 0.32 mg/kg. |
