摘要
[目的]测定云南建水草牙(Typha latifolia L.)中8种金属元素的含量,以期为这一资源的开发利用提供科学依据。[方法]采用火焰原子吸收光谱法测定草芽中的Fe、Zn、Cu、N i、Co、Cd、Pb和Cr元素的含量。[结果]建水草牙含有多种对人体有益的矿物元素,7种金属元素含量顺序为Fe>Zn>Cu>N i>Co>Cd>Pb,Cr未检测出;Fe元素含量较高,而Cu含量相对较低。[结论]建水草牙含矿物元素较丰富。
[Objective] To determine the content of 8 metal elements in Typha latifolia L.from Jianshui County of Yunnan Province,so as to provide a scientific basis for development and utilization of this resources.[Method] Contents of 8 metal elements including Fe,Zn,Cu,Ni,Co,Cd,Pb and Cr were determined by flame atomic absorption spectrometry.[Result] Typha latifolia L.was rich in various mineral elements to human health.The content order of 7 analyzed mineral elements was FeZnCuNiCoCdPb.Cr element could not be detected in tested sample.The content of Fe was higher in Typha latifolia L.,while Cu was relatively lower.[Conclusion] There were abundant mineral elements which were necessary for people in the Typha latifolia L..
