| 摘 要： | 采用高效液相色谱分离,荧光检测器检测,建立了三种不同类型的玩具中苯酚和双酚A的测定方法.用超声提取的方式处理样品,对提取溶剂和提取时间进行选择,确定以甲醇-水(65:35,V/V)作为提取溶液,超声提取20 min.苯酚和双酚A分别在0.012～1.0 mg/L、0.03～2.5 mg/L范围内线性良好,相关系数均达到0.9999,检出限分别为0.6 mg/kg和1.5 mg/kg,不同加标水平的回收率为90.5%～104.3%,其相对标准偏差为0.4%～3.8%.该方法操作简便,灵敏度高、重现性好,能有效提取和测定三类玩具中的苯酚和双酚A.

| Abstract: | An analytical method of high performance liquid chromatography-fluorescence detection(HPLC-FL) has been established for the determination of phenol and bisphenol A in toys.The samples were extralted by ultrasonic extraction using methanol-water(65/35,V/V) as extractunt for 20 min.The average recoveries(n=10) were from 90.5% to 104.3% with relative standard deviations between 0.4%~3.8%.The detecton limits of phenol and bisphenol A were 0.6 mg/kg and 1.5 mg/kg,respectivily.The method is simple,reproducible,se... |
