| 摘 要： | 稀土元素是人体重要的营养成分,但是含量高时又会对人体造成危害.现应用ICP-MS分析了冬枣果实中稀土元素的含量.结果表明:冬枣果实中含有9种稀土元素:La、Ce、Pr、Nd、Sm、Eu、Gd、Th和U,它们的浓度分别是1.46、2.45、0.34、1.06、0.25、0.07、0.21、0.44和0.26ng/g,说明冬枣中稀土元素处在一个较低水平.稀土元素在冬枣果实中的积累规律的机理还需要进一步研究.

| Abstract: | Rare earth elements are the important elements of human body,but they are harmful to health at high concentration.Contents of rare earth elements in Chinese winter jujube fruit were analyzed by ICP-MS,the results showed that there were 9 kinds of rare earth elements: La,Ce,Pr,Nd,Sm,Eu,Gd,Th and U in Chinese winter jujube,whose contents were 1.46 ng/g,2.45 ng/g,0.34 ng/g,1.06 ng/g,0.25 ng/g,0.07 ng/g,0.21 ng/g,0.44 ng/g and 0.26 ng/g respectively.But the absorption mechanism of rare earth elements needs to be further studied. |
