The isotope effect of sodium-ion in countercurrent electromigration (Klemm's method) has been investigated for a system of fused sodium nitrate labelled with the radioactive nuclide <SUP>22</SUP>Na. Two runs were made (Experiments A and B, respectively). In Experiment A, the fused salt chain, Al(cathode)-NaNO<SUB>3</SUB>-Pt(anode) was electrolyzed for 20 hr at 340 ?? with a current density of 1.3 A/cm<SUB>2</SUB> in the separating tube. In Experiment B, electrolysis was carried out for 67 hr at 380 ?? with a current density of 1.5 A/cm<SUB>2</SUB> in the separating tube. After electromigration, a change was observed in the specific activity of sodium in the separating tube. The elementary process separation factor, defined as the ratio of the mobilities of the isotopic ions, i.e., V<SUB>Na-22</SUB>/V<SUB>Na-23</SUB>, was calculated to be 1.0023 for Experiment A and 1.0017 for B. The mass effect for sodium ion in fused sodium nitrate was calculated to be -0.045±0.006 (standard deviation).
