| 摘 要： | 采用微波消解及ICP-MS,建立了一种测定二色补血草中Be,B,Na,Al,Mg,P,K,Ca,V,Cr,Mn,Fe,Co,Ni,Cu, Zn,Ga,As,Se,Sr,Mo,Cd,Ba,La,Hg,Pb和Th共27种元素的方法.实验采用国家一级标准物质茶叶(GBW-07605)评价了方法的准确性,通过在线加入Ge,In和Bi三种元素内标液的方法来校正由于基体效应和信号漂移对测量所造成的影响.方法的回收率为92.4%～107.2%,相对标准偏差为1.5%～9.7%,检出限为0.002～0.081 μg·L-2,元素的测定结果表明:二色补血草中含有丰富的Na,K,Ca,Mg和P等常量元素,Fe,Mn,Zn,Cr和Cu等微量元素.实验结果为深入研究二色补血草无机元素与药效的相关性提供了参考数据. |

| Abstract: | An inductively coupled plasma mass spectrometry (ICP-MS) for determination of the contents of 27 inorganic elements in Limonium bicolor after microwave digestion of the sample was developed. The accuracy of the method was evaluated by the analysis of corresponding inorganic elements in standard reference materials (GBW 07605),and matrix effect and signal drift were compensated by using the internal standard elements (Ge,In and Bi). By applying the proposed method,the contents of 27 inorganic elements in Lim... |
