Abstract A separative elution of uranium from an amidoxime polymer which had been immersed in seawater was examined on its relation with the flow rate of acidic eluent. The elution with 0.5 M HC1 at S.V. ≤ 1 h−1 or with 1.0 M HCl at S.V. ≤ 3 h−1, which was started from the elution by 16.5 L/L p of 0.1 MHCl at S.V. ≤ 3 h−1, provided an eluate containing more than 80% of uranium adsorbed and separating from other metal ions except Fe(III) and Cu(II). The efficiency of uranium elution was hardly affected by the scale of the system employed. Acid consumption, which occurred predominantly in the elution with 0.1 M HCl, was ∼1.4 mol/L p . The results suggest that this elution method is promising in the recovery of uranium from seawater.
