摘要

检测双酚A最普遍的是使用高效液相色谱法,其简便、快速、高效、准确。本文采用高效液相色谱法(HPLC)对塑胶玩具及儿童用品中的双酚A(BPA)的含量进行了测定。样品用四氢吠喃沉淀法提取,以甲醇-水为流动相进行分离,检测波长为226 nm,外标法定量。本方法的检出限为1 ng。
        The most common method for the determination of bisphenol A is high performance liquid chromatography, which is simple, rapid, efficient and accurate. The content of bisphenol A(BPA) in plastic toys and children's products is determined by high performance liquid chromatography(HPLC).The samples are extracted by tetrahydrobark precipitation method and separated by methanol-water as mobile phase. The detection wavelength is 226 nm and quantified by external standard method. The detection limit of this method is 1 ng.
