Separation of Uranium from Liquid Media

Groundwater Remediation Uranium is a natural element found in groundwater throughout the world and regulated in some countri Uranium is usually present as the monovalent uranyl ionic complex (U 3 O 8-) at very low levels in groundwater and thus the most cost effective treatment is to remove the uranium with a highly selective ion exchange resin and then dispose of the uranium-loaded resin
