| 摘 要： | 目的]考察不同消解方法对蒲公英中Fe、Zn、Cu、Mn元素含量测定的影响。方法]分别通过干法、湿法、微波法处理样品,利用原子吸收分光光度计测定样品中的4种元素含量。结果]用微波法消解样品时,测得Cu、Zn、Fe、Mn含量分别为35.01、103.11、210.86、21.13μg/g,高于干法和湿法这2种消解方法处理。结论]微波消解法适合用于植物样品微量元素测定的前处理。

| Abstract: | Object] To investigate the effects of different digestion procedures on microelements contents(Fe,Mn,Zn,Cu) in Taraxacum mongolicum Hand.-Mazz..Method] The Taraxacum mongolicum Hand.-Mazz.samples were treated by dry,wet and microwave methods respectively,and the contents of Fe,Mn,Zn,Cu were determined by atomic absorption spectrometer(AAS).Result] The contents of Cu,Zn,Fe,Mn were the largest in microwave treated sample,which achieved 35.01,103.11,210.86,21.13 μg/g respectively.Conclusion] Microwave method was proved to be suitable for pretreating plant samples. |
