摘　　要：利用ICP-MS法测量黍米黄酒中9种营养元素与5种污染元素。采用微波消解的前处理方法,通过电感耦合等离子质谱法进行测量。结果表明,该方法的线性系数均在0.999以上,各元素检出限均低于国家相关标准,加标回收率的范围86.40%~109.80%,相对标准偏差(RSD)范围为1.1%~3.5%。结果表明,代县黍米黄酒中各元素的含量存在差异。In this study,9 kinds of nutrient elements and 5 kinds of pollution elements in millet Huangjiu were determined by ICP MS combined with microwave digestion.The linear coefficients of the method were above 0.999,and the detection limits of each ele-ment were lower than relevant national standards.The spiked recoveries ranged from 86.40%to 109.80%,and the relative standard deviations(RSD)were between 1.1%and 3.5%.In conclusion,there are differences in the contents of elements in Daxian millet Huangjiu.
