We have been making a study on the extraction of uranium from seawater with the composite adsorbent which consists of hydrous titanium oxide and activated carbon.
In this paper, the titanium-activated carbon flocculent adsorbents were prepared with PAH (polyacrylic acid hydrazide) as a binder, and the uranium adsorptivity of the flocculent adsorbents was examined in seawater. The flocculent adsorbents were found to show a high rate of adsorption for uranium similar to the powdery adsorbent and to adsorb 0.1 mg-U/g for 5 days from natural seawater
