For the purpose of recovering uranium from sea water, the study has been made on the adsorption of uranium in artificial sea water with powdered titanic acid. Foam separation process has been proposed which is composed of adsorption with powdered titanic acid and ion flotation. In the experiment of adsorption, the apparent adsorption rate coefficient of combined process proved to be larger than that of continuously stirring system. The relation between uranium adsorbed capacity and concentration of uranium in the solution was arranged by Freundlich's equation. Recovery of uranium from sea water was found to be about3,000μg-U/g-Ad in 15 days stirring. Advisable condition of combined separation process is shown as follows:
1. Surface active agent...DBS,
2. Concentration of DBS...1.0mg/l,
3. Gas velocity...0.25cm/sec.
Separation of powdered titanic acid from bulk liquid was recovered 90% by flotation with DBS concentration of 150mg/l.
