| 摘 要： | 采用电感耦合等离子体质谱法研究了中草药磨盘草中8种微量元素（Ca、Mg、Zn、Fe．Mn、Cu、Ni、Cr）的次级形态．结果表明，通过阳离子交换树脂分离，8种元素成分主要以游离态形式存在，少量以非游离态存在；通过氯仿萃取，8种元素成分大多为元机结合态，少量为有机结合态；LSC-500螯合柱分离表明Ni、Zn的稳定态成分较多（88．89％，61．79％），而其他元素是不稳定态成分较多．

| Abstract: | The second speciation of eight trace elements(Ca,Mg,Zn,Fe,Mn,Cu,Ni,Cr) in Abutilon indicum(L.) Sweet were studied by ICP-MS.The results showed that eight trace elements exist mainly in free ions forms and a few in non-free ions forms after the separation of cation exchange resin;Eight trace elements exist mostly in inorganic forms and a few in organic forms after extraction of CHCl3;After the separation of LSC-500 Chelating resin,the contents of Ni and Zn in stable form are higher(88.89%,61.79%),but the con... |
