摘要：

The lanthanide elements and isotopes are analytes of significant interest for several nuclear-related fields, for example nuclear waste treatment, nuclear forensics, and nuclear safeguards. 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 spectrometry, e.g. Tb-161. This work presents an optimized method for the isolation of individual rare earth elements using LN resin.
