摘要

建立了微波消解/电感耦合等离子体质谱法同时测定粮食和蔬菜中11种重金属元素(Cu、Mn、Cr、Pb、Cd、Ni、Sb、Hg、Co、Ag、As)的方法，优化了微波消解条件和仪器测定条件，采用HNO3-HF-H2O2和HNO3-H2O2两种混酸体系，将样品进行完全消解。结果显示，11种金属元素的线性系数不小于0.999 5，方法的检出限为0.001~10.00 μg/L，测定的相对标准偏差(RSD，n=5)不大于5.0%。该方法具有快速、简便、灵敏度高、稳定性好、准确度高等优点。

Abstract

In this paper,a method was established for the analysis of 11 heavy metal elements(Cu，Mn，Cr，Pb，Cd，Ni，Sb，Hg，Co，Ag，As) in grain and vegetables using inductively coupled plasma mass spectrometry(ICP-MS) with microwave digestion.The instrumental parameters and microwave digestion conditions were optimized.Samples were digested completely using HNO3-HF-H2O2 and HNO3-H2O2.And the results showed that the linear correlation cofficients of eleven elements(r) were not less than 0.999 5,the limits of detection were in the range of 0.001-10.00 μg/L and the relative standard deviations(RSD，n=5) were not more than 5.0%.This method has the advantages of rapidness,simplicity,high sensitivity,good stability and accuracy.
