| 摘 要： | 应用火焰原子吸收光谱法测定了6种温里类中草药(即香附子、干姜、肉桂、细辛、高良姜及小茴香)中4种痕量元素铜、铁、锌及锰的含量。样品用硝酸-高氯酸(4+1)混合酸消解后加入过氧化氢,并蒸发至近干,残渣溶于硝酸(1+99)溶液中后用于火焰原子吸收光谱法分析,标准曲线分别用上述4种元素的标准溶液制作。按此方法分析了上述6种中草药中铜、铁、锌及锰4种痕量元素,并在此基础上用标准加入法作了回收试验,测得4种痕量元素的回收率在93.5%~109.0%之间。

| Abstract: | Four trace elements(Cu,Fe,Zn,Mn) in 6 kinds of Chinese herbal medicines,i.e.,cyperus rotundus,rhizoma zingiberis,cortex cinnamomi,azarum sieboldii miq.,rhizoma alpiniae officinarum and fructus foeniculi,were determined by FAAS.Samples of the Chinese herbal medicines were digested with HNO3-HClO4(4+1) mixture,and then evaporated to near dryness after adding H2O2.The residue was taken up with HNO3(1+99) and used for FAAS analysis.Standard curves were prepared separately with standard solutions of the 4 elemen... |
