Abstract
Both before and after adsorption of uranium from sea water, the concentrations of various elements on titanium-activated carbon composite adsorbent were determined by spark source mass spectrometry. From the results, the behaviors of sea water constituents in uranium adsorption process were discussed. Adsorptivity of the adsorbent for sea water constituents was evaluated by concentration factors which were calculated from element concentrations in the adsorbent and sea water. The order of adsorptivity for sea water constituents was as follows:
alkali metals, halogens, sulphur<boron, alkaline earth metals <phosphor, arsenic<transition metals, uranium
