俄罗斯科学院乌拉尔分院机械科学研究所切克豪莫娃等提出一种用磷酸锆作无机离子交换剂提取和分离Sm(Ⅲ)与Nd(Ⅲ)的方法。通过水合碳酸铵和水合碳酸锆生成络合物获得了磷酸锆。Sm/Nd分离因子为(0.2～0.4)×10~(-6)。发展了一种可用于质谱测定的从天然样品(矿物)提取并分离Sm(Ⅲ)与Nd(Ⅲ)的方法。
Russia’s Academy of Sciences Ural Branch Institute of Mechanical Science Cherkhao Mo and put forward a kind of inorganic zirconium phosphate ion exchange agent for the separation and separation of Sm (Ⅲ) and Nd (Ⅲ) method. Zirconium phosphate was obtained by the formation of a complex of hydrated ammonium carbonate and hydrated zirconium carbonate. Sm / Nd separation factor of (0.2 ~ 0.4) × 10 ~ (-6). A method for the extraction and separation of Sm (Ⅲ) and Nd (Ⅲ) from natural samples (minerals) has been developed for mass spectrometry.
