Abstract
With use of fibrous cation exchanger modified by introducing titanic acid, a study on recovery of trace uranium and radium in the waste water from uranium mines was carried out.
The fibrous adsorbent was proved to have an enough adsorption capacity for neutral or weak alkaline uranium solution such as mine water, rain leach water, dam water and so on.
Adsorption of a trace amount of radium in the waste water from uranium refining process was also investigated.
Using the granular adsorbent composed of fibrous adsorbent, field adsorption experiments were carried out with column system.
It was revealed that both uranium and radium are efficiently captured from the waste water of the uranium refining process of the Power-Reactor and Nuclear Fuel Development Corporation at the Ningyo Toge Mine.
