摘　　要：采用硝酸处理富硒灵芝,经微波消解后,以在线内标法利用电感耦合等离子体质谱测定富硒灵芝中22种元素含量。结果表明,22种元素在0.5~100.0μg·L^(-1),线性回归方程的相关系数大于0.9995,定量限为0.080~1.600μg·kg^(-1),回收率为89.6%~111.5%,相对标准偏差为0.7%~5.3%。Se-enriched Ganoderma Lucidum was treated with nitric acid and digested by microwave.The content of 22 elements in Se-enriched Ganoderma Lucidum was determined by inductively coupled plasma mass spectrometry(ICP-MS)with online internal standard method.The results show that 22 elements range from 0.5 to 100.0μg·L^(-1),the correlation coefficient of the linear regression equation is greater than 0.9995,and the quantification limit is 0.080~1.600μg·kg^(-1);The recovery rate is 89.6%~111.5%,and the relative standard deviation is 0.7%~5.3%.
