ICP-OES法测定花锚和椭圆叶花锚中的21种矿物元素
Determination of 21 Mineral Elements in Halenia corniculata and Halenia elliptica by ICP-OES
摘要
Abstract
Twenty-one mineral elements of Halenia corniculata and H.elliptica were tested by ICP-OES in this study.H.corniculata and H.ellipticaare the only existing species of genus Halenia (family:Gentianaceae) distributed in China.According to dates,the correlation coefficients are all greater than 0.9990,which showed a good linearity.The recovery rates were in the range of 86％-106％ and the RSD were all below 4.35％,which indicated good accuracy and precision.The results showed that both of them contained rich mineral elements,especially Ca,Mg,Fe.The content of Ca,Mg in H.elliptica were higher than that in H.corniculata,especially Ca,which was 1.6 times as much as in H.corniculata.The 8 elements,namely Be,Cd,Co,Li,Mo,Pb,Sb,T1,were almost equal in both plants.In addition,contents of rest elements in H.corniculata were higher than that of H.elliptica.Combined with corresponding background values of soil elements,it was concluded that the contents of elements were related to growing environment of plants.By comparing differences in elemental contents between H.corniculata and H.elliptica,it can provide some basis for further study and usage.关键词
