建立了进出口建筑用环氧树脂粘接剂中双酚A的高效液相色谱-荧光检测法。对提取方法和色谱条件进行了研究,结果表明采用乙醇超声提取样品15min可获得良好的提取效果。以乙腈和水为流动相,采用梯度洗脱可消除样品的基质干扰。方法对环氧树脂粘接剂中双酚A的定量限(LOQ)为0.5 mg/kg,在2～4000 ng/mL范围内,线性相关系数为0.9996。在5个添加水平下回收率在89.1%～100.8%之间。
The establishment of the import and export of epoxy resin adhesive building bisphenol A high performance liquid chromatography - fluorescence detection method. The extraction methods and chromatographic conditions were studied. The results showed that ultrasonic extraction of ethanol samples 15min to obtain good extraction results. Using acetonitrile and water as mobile phases, the gradient elution can eliminate matrix interference of samples. Method The limit of quantification (LOQ) for bisphenol A in epoxy adhesives was 0.5 mg / kg, with a linear correlation coefficient of 0.9996 in the range of 2 to 4000 ng / mL. The recoveries were between 89.1% and 100.8% at the five addition levels.
