| 摘 要： | 建立了高效液相色谱分析食品罐内涂料中双酚A(BPA)和双酚F(BPF)环氧衍生物的方法.样品经乙腈提取后,旋转蒸发浓缩至干,以V(乙腈)∶ V(水)=50∶ 50混合液溶解并定容;采用Lichrospher C18柱,以乙腈/水为流动相梯度洗脱,进行高效液相色谱分离;荧光检测器检测,激发波长230 nm,发射波长301 nm.在2.3～230 μg/L浓度范围内,各BPA和BPF环氧衍生物的响应峰面积与其相应浓度呈良好相关性,检出限为0.57～6.55 μg/L;在80～400 μg/L添加水平范围内,平均添加回收率为85%～107%;相对标准差小于7.4%.结果表明,本方法适用于食品罐内涂料中BPA和BPF环氧衍生物残留分析.

| Abstract: | A method was developed for determining residual bisphenol A(BPA),bisphenol F(BPF) and their epoxy derivatives by high performance liquid chromatography.Samples were extracted with acetonitrile and then extracts were dried and dissolved in acetonitrile-water(50/50,V/V).For the HPLC determination,a Lichrospher C18 column was employed and mixture of acetonitrile-water was used as the mobile phase under fluorescence detector with excitation and emission wavelengths of 230 nm and 301 nm,respectively.The peak are... |
