摘要
采用微波消解,ICP-MS法测定国内10种调味料中有毒和必须金属元素含量,测定标准物质对方法进行确证。结果表明,方法的相对标准偏差小于5%,回收率在83.4%~115%之间。调料中K、Ca、Mg、Mn、Fe含量丰富,生姜中As含量较高,桂皮和花椒中Pb含量高。
Toxic and essential metal element content of ten different spices of China were determined by ICP-MS after microwave digestion method.The validation of the presented procedure is performed by the analysis of standard reference material.The relative standard deviations were found to be lower than 5%,and the recovery values were 83.4%~115%.The contents of K,Ca,Mg,Mn,Fe are rich in all the spices,the content of As is high in ginger and the content of Pb is high in cassia and prickly ash.
