| 摘 要： | 探讨高效液相色谱法测定塑料食品接触材料中壬基酚含量的可行性。样品用正己烷超声波萃取后,氮吹至干,用甲醇定容后离心,上清液采用高效液相色谱分析,用外标法定量。在本试验条件下,壬基酚线性关系良好,相关系数为0.9992,检出限为0.05mg/kg,回收率为90.0%~93.9%,RSD值为2.12%~3.82%。

| Abstract: | A method of simultaneous determination of nonylphenol in plastic food contact materials by High Performance Liquid Chromatography(HPLC)was built and its feasibility was investigated. The samples were extracted with N-hexane,dried by nitrogen blow,centrifuged after the volume was fixed with methanol and then analyzed by HPLC,and quantified by external standard method. The method has good linearity and its linear correlation coefficient is 0.9992,the detection limit is 0.05 mg/kg,the recovery rate is 90.0%~93.9% with relative standard deviation(RSD)of 2.12%~3.82%. |
