【摘要】 本文用ICP——AES(电感耦合等离子体发射光谱法)测定了安徽省六种典型土壤中的十六种稀土元素。测定结果表明,安徽省土壤中稀土含量以轻稀土元素为主,镧系元素的含量依各元素的原子序数呈奇偶分布,从La到Lu,元素分布量呈波浪式下降趋势,这与地壳中镧系元素丰度和原子序数间的关系是一致的。更多还原

【Abstract】 The content of sixteen rare earth elements in the soils of Anhui Province were determined with ICP-AES. Results show that most Of the sixteen RE in this province are light ones, and that the contents of the elements in lanthanide series are basically magatively proportional to their atomic numbers. This appears to be the same as the relation between the clarke values of lanthanide elements and their atomic numbers.更多还原
