目的：选择电感耦合等离子体发射光谱法（ICP-AES）测定甘草中多种共存微量元素的最佳前处理方法。方法分别用湿式消化法、微波消解法和高温灰化法前处理甘草样品，在相同的测定条件下用ICP-AES测定甘草中铜（Cu）、镍（Ni）、锰（Mn）、铅（Pb）和硒（Se）5种元素。结果从3种不同样品处理方法看出，Cu、Ni、Mn元素测定值3种方法均有很高的回收率（99.46%～101.50%）；与湿式消化法和微波消解法比较，高温灰化法对于具有汽化温度较低的元素Pb、Se的回收率偏低（70.52%、62.01%）。高温灰化法测定处理后，各元素含量均低于温湿式消化法或微波消解法，差异有统计学意义（P<0.05）。结论采用湿式消化法或微波消解法处理样品后用ICP-AES法测定甘草中Cu、Ni、Mn、Pb和Se元素含量，能得到满意的结果。

Objective To select inductively coupled plasma atomic emission spectrometry (ICP-AES) to determine the most optimum method of detecting multiply coexistence microelement in glycyrrhiza uralensis. Methods It adopted wet air di-gestion method,microwave digestion method and high temperature ashing method to test the 5 microelements such as Cu ,Ni,Mn, Pb and Se under the same determination condition. Results From the above-mentioned sample disposal menthods,it came out that it has a high recovery rate in the elements of Cu,Ni and Mn,accounting for 99.46%~101.50%. Compared to the wet air di-gestion method and microwave digestion method ,the high temperature ashing method had a low recovery rate in the elements of Pb,Se with low vaporization temperature,accounting for 70.52%and 62.01%respectively. After diposal of high temperature ash-ing,the contents of the above elements were lower than those by wet air digestion method and microwave digestion method. Con-clusion Satisfactory results may be obtained by the wet air digestion and microwave digestion methods to dispose the glycyrrhiza uralensis samples and to test the elements such as Cu、Ni、Mn、Pb and Se in it.
