摘要
采用高效液相色谱-荧光法对肉类塑料包装物中7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、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,用高效液相色谱、荧光检测器对肉类塑料包装物中7种环境雌激素的测定。结果表明:该方法样品平均加标回收率为90.4%～105.7%,相对标准偏差为1.63%～8.15%;塑料食品包装物中11种环境雌激素的检出限为0.071～0.220mg/kg。
An HPLC-FLD method was developed to determine 7 environmental estrogens in met packaging materials. Samples were dissolved in dichloromethane and precipitated by adding methanol. The filtrate was cleaned up on C18 SPE column and separated by high performance liquid chromatography, and detected with a fluorescence detector （FLD）. Average spike recoveries between 90,4% and 105.7% and relative standard deviations （RSD） between 1.63% and 8.15% were obtained for spiked samples. The limits of detection （LOD） of the HPLC method were between 0.071 mg/kg and 0.22 mg/kg.
