通过GF-AAS分析技术,采用标准加入法,对基体效应、基体改进剂、共存元素干扰、仪器分析参数等因素的研究,确定分析的最佳条件,建立了与食品接触不锈钢制品中痕量铅迁移量测定的方法。结果表明,该分析方法准确、可靠、操作性强;检出限为0.2μg/L;相对标准偏差在1.9%~3.1%之间;回收率在95%~107%之间。 By GF-AAS analysis technology, the standard addition method, the matrix effect, the matrix modifier, the coexistence of elements interference, instrument analysis parameters and other factors to determine the best analysis of the conditions established with the food contact with trace amounts of lead in stainless steel products Method of migration measurement. The results showed that the method was accurate, reliable and easy to operate. The detection limit was 0.2 μg / L, the relative standard deviation was between 1.9% and 3.1%, and the recovery was between 95% and 107%.
