Abstract
Adsorption of uranium on fluidized amidoxime-resin beads from seawater was explored by usingan adsorption apparatus manufactured for this study. The adsorption rate of uranium on theamidoxime-resin beads did not depend on the flow rate of seawater over the range 60-240 h-1. Steady fluidization of the amidoxime-resin particles was observed at a seawater flow rate of 10-30cm min-1. Under the condition of the steady fluidization, the adsorption of uranium was successfullycarried out over approximately one year, the extent of uranium recovery being 76% in the summer season and 41% in the winter season.
