微波消解ICP-AES法测定甘草中常量及微量元素

Determination of Contents of Macro-and Trace-Elements in the Glycyrrhiza uralensis Fisch by Microwave Digestion ICP-AES Method

用微波消解甘草后，采用美国利曼公司生产的PS-Ⅰ型中阶梯光栅光谱仪测定甘草中的常量及微量元素，结果表明，其相对标准偏差为3.17%-7.87%，回收率为92%-102%.

After Glycyrrhiza uralensis Fisch were digested by microwave, the contents of macroelements and trace elements in it were determined by ICP/Echelle spectrometer （American Leeman labs）. The results showed that the relative standard deviation of this measurement was 3. 17%-7.87%, the recovery rate of samples was 92%-102%.
