The Cs/sup +/ and Ba/sup 2+/ ions transferred to the cathode cell from the feed cell at lower (1.0 to 0.5N) concentrations of HNO3. It was shown that the transfer rate at the lower acidities has little dependency upon feed cell acidity. Graphical representations are given of results on the electrodialysis of Ce - Pr/sup 144/ in HNO/sub 3/ solutions. Less transfer was observed from HF for Ce - Pr/sup 144/, which may be attributed to the colloidal CeF/sub 3/ formation. Zr - Nb/sup 95/ transfers to the anode cell at a relatively slow rate and incompletely at low (0.5 to 0.25N) HNO/sub 3/ concentrations. A faster and more complete transfer occurs in oxalic acid at 1.0 to 0.5N. The best transfer rates were obtained in 1.0 to 0.5N HF. The results are tabulated for 2N HF showing the relative percent of initial isotope activity in the cells. (B.O.G.)
