PMBP螯合萃取剂因其良好的选择性而被广泛应用于稀土元索的分离富集。笔者在文献中描述了试样经化学预处理后,用PMBP树脂柱上萃取富集稀土总量,薄膜制片,X射线荧光光谱测定岩石土壤中15个稀土分量的方法。在实际工作中,也参照文献所述PMBP溶剂萃取方式进行富集,得到同栏效果。但在分析含锰较高的岩石样品时,发现Mn对Eu、Dy、Tm、Lu四个重稀土元素的影响是不可忽视的。而Eu在稀土地球化学研究中起举足轻重的作用。本文着重探讨Mn的影响及消除方法。试验部分一仪器与试剂
PMBP chelating extractant is widely used in the separation and enrichment of rare earth elements cable because of its good selectivity. The author described in the literature after the chemical pretreatment sample, the PMBP resin column enrichment of total rare earth, film production, X-ray fluorescence spectrometry determination of 15 rare earth elements in rock. In practical work, reference is also made to the PMBP solvent extraction method for enrichment to obtain the same column effect. However, when analyzing rock samples with high manganese content, it is found that the influence of Mn on four heavy rare earth elements such as Eu, Dy, Tm and Lu can not be neglected. Eu plays a decisive role in the study of rare earth geochemistry. This article focuses on the impact of Mn and elimination methods. Test part of an instrument and reagents
