| 摘 要： | 用原子吸收光谱法对银杏叶中十三种矿物元素进行了分析测定,结果显示,本方法精密度和回收率较好.在选定的实验条件下,银杏叶中各元素间相互不干扰,可在一份样品液中进行13种元素的分别测定;所测银杏叶中含有丰富的Ca、K、Mg、Fe、Mn、Zn以及Cu、Ni,有毒金属Pb、Cd被检出,加标回收率在86.03%-113.81%之间,RSD≤3.6(n=6).

| Abstract: | Thirteen elements in leaves of Ginkgo biloba were determined by atomic absorption spectrophotometer.The result shows that the RSD and recovery are better,and leaves of Ginkgo biloba L contains many essential elements among which the contents of Ca,K,Mg,Fe,Mn and Zn are higher than those of Ni and Cu.but Pb and Cd were determined.The experimental results showed that the RSDs(n=6) all smaller than 3 59%,and the addition standard recovery(ASR)(n=6) was 86.03%-113.81% for all elements. |
