| Abstract: | Abstract Strontium isotopes were fractionated using liquid chromatography with a cryptand (2B,2,2) polymer as a stationary phase. In this study, we observed that the single stage isotope enrichment factor of 84Sr shows the following order, water6.4×10?3]>MeOH4.9×10?3]>DMF1.1×10?3]. The enrichment factors observed in this study did not show a mass‐dependent profile, indicating that the mass‐independent isotope effect affects isotope enrichment phenomena. The mass‐dependent and the mass‐independent isotope effects that influence the enrichment factor of 84Sr are related to the donor number linearly, implying that the solvation strongly affects the isotope effect. |
