摘要
建立了食品用粘合剂、塑料瓶等高分子食品接触材料中可溶性铅、镉、砷、汞和含量的电感耦合等离子体质谱检测方法。样品中铅、镉、砷、汞的可溶部分溶解在0.07mol/L的盐酸(模拟人体胃酸)中,用电感耦合等离子体质谱检测,内标法定量。在0.5μg/L~100μg/L添加水平,回收率在88.6%~98.3%之间,精密度在1.8%~5.1%之间。
A method was developed for the determination of the soluble Pb, Cd, As and Hg in the polymer of food contact materials by inductively coupled plasma-mass spectrometry (ICP-MS). Samples were extracted by 0.07 mol/L hydrochloric acid solution, and then analyzed with ICP-MS. Within the range of 0.5 μg/L-100 μg/L, recoveries and RSD were 88.6%-98.3% and 1.8% -5.1%, respectively.
