Abstract
In the course of studies on the recovery of uranium from sea water by using hydrous titanium oxide as adsorbent, the recovery by adsorption of other rare elements was also investigated. The adsorption of lithium and vanadium was found to be too small to allow recovery, but the adsorption of strontium was sufficient for recovery. Effective strontium desorption was found to be possible with acids but not with alkali carbonate, the desorption agent most commonly used for uranium desorption. The amount of adsorbed strontium and calcium increased in each cycle of uranium adsorption and desorption, while no significant increace was found in the amount of magnesium adsorption after the first cycle when post-washing with fresh water was conducted.
The ratio between the quantities of strontium and calcium adsorbed was constant, and was the same as that in the sea water.
