Sorption of Uranium(VI) and Thorium(IV) by Jordanian BentoniteThe primary objective of this study is the sorption of uranium and thorium by purified Jordanian bentonite from AlAzraq at different pH =,, and, at different temperature °C, °C, and °C, and different contact time. The purifiion of raw bentonite will be done by the removal of quartz.
Method of extracting uranium, radium, and vanadium from ...The method of treating ores containing uranium, vanadium and radium, which comprises mechanically reducing said ores to a relatively finely divided state, treating the reduced ores with a solution of an alkali carbonate and agitating same to insure complete surface contact between the two, washing the treated ores and solution with upward flowing currents of water to separate the solution and ...
UraniumGroundwater Remediation . Uranium is a natural element found in groundwater throughout the world and regulated in some countries. 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 uraniumloaded resin.
