中文摘要: 为了研究湖州表层土壤样品中稀土元素的分布特征,利用ICP-MS测定了土壤中稀土元素的含量。结果表明湖州表层土壤中稀土元素含量的大小顺序为:Ce>La>Nd>Pr>Sm>Gd>Dy>Yb>Er>Eu>Ho>Tb>Tm>Lu,遵循Oddo-Harkins法则。湖州表层土壤中稀土元素的分量均值和总量均值皆高于全国水平,稀土元素存在显著的分馏现象,轻稀土元素明显富集。表层土壤中Ce和Eu都有部分亏损。
Abstract:In order to study the distribution characteristics of rare earth elements (REEs) in surface soils from Huzhou, ICP-MS was used to determine the contents of rare earth elements in soils. The results showed that the contents of rare earth elements in surface soils from Huzhou were in an order of Ce>La>Nd>Pr>Sm>Gd>Dy>Yb>Er>Eu>Ho>Tb>Tm>Lu which followed the Oddo-Harkins rule. The branch concentrations and the total concentrations of REEs in surface soils from Huzhou territory are higher than those of REEs in the surface soils collected from the whole country. A distinct fractional distillation phenomenon for REEs and obvious enrichment effect for light REEs were observed. Ce-anomalies and Eu-anomalies were partially depleted in surface soils in Huzhou.
