火焰原子吸收光谱法测定牛肝菌中金属元素的含量
Determination of Fe ,Ni ,Ca ,K ,Cd ,Cu.Zn,Mn and Cr in Boletus by Flame Atomic Absorption Spectrophotometry
摘要
运用火焰原子吸收光谱法测定牛肝菌（Cows bacilli）中的金属元素Fe、Ni、Ca、K、Cd、Cu、Zn、Mn、Cr 9种离子的含量。由测定结果显示,每100g牛肝菌中不含有镉、铜等元素,而铁、镍、钙、钾、锌、锰、铬的含量分别为0.341mg,0.030mg,0.596mg,0.043mg,0.074mg,0.053mg.,0.230mg。且测得Fe、Ni、Ca、K、Cd、Cu、Zn、Mn、Cr 9种元素的相对标准偏差分别为1.7498%、3.7584%、3.6056%、5.1036%、5.3571
