The lanthanide elements and isotopes are analytes of significant interest for several nuclear-related fields. Chemical separation among these elements is uniquely challenging due to their nearly identical chemical properties. This difficulty in interelement separation can create obstacles for quantitative radiometric analysis, specifically for isotopes without distinct energy emissions easily measured by gamma spectroscopy, for example Tb-161. Presented in this work is an optimized method for the isolation of individual rare earth elements using Eichrom’s LN resin.
