摘要
东北大豆是我国重要的自然资源,而东北大豆种子中稀土元素含量未见报道。应用ICP—MS对东北7个主栽大豆品种中的稀土元素进行了初步分析。结果表明7个品种大豆种子中检测到13种稀土元素,含量一般都在0～20 ng/g之间,含量超过1 ng/g的稀土元素含量的顺序是Ce>La>Nd>Pr>Eu>Sm>Gd。
Dongbei soybean is one of the most important plant resources in our country,but the content of rare earth elements in soybean seed has not be reported.Contents of rare earth elements in 7 soybean species from Northeastern China were studied by ICP—MS.The results showed that Northeastern soybean contained 13 kinds of rare element,the contents range from 0～20 ng/g,rare earth elements more than 1 ng/g are CeLaNdPrEuSmGd.
