马兰草中微量元素研究

Studies of Trace Elements of Malan Straw

目的:对不同产地马兰草中微量元素含量进行考察。方法:用原子吸收分光光度法和原子荧光分光光度法测定马兰草中Cu、Se、Hg、Pb、Cd、As、Cr的含量。结果:不同产地马兰草中微量元素含量有显著性差异。结论:大转弯的马兰草中有害微量元素含量最低,有益微量元素含量最高。

Objective： Studies on seven trace elements of Malan Straw in different regions Method： To determining seven trace elements（Pb、Cd、Cr、Cu、Hg、Se、As）of Malan Straw with atomic absorption spectrophotometry and atomic fluorescence spectrophotometry.Results： the content of even trace elements of Malan Straw in different regions was distinct differences.Conclusion： It is suggested that the content of harmful trace elements of Malan Straw in Dazhuanwan district were lower,and that of beneficial element were higher than any other district.
