Abstract
Resins with monoamides as functional groups have been synthesized and their fundamental adsorption behaviors have been examined for selective recovery of uranium(VI) from nitric acid media. The resins synthesized with porous silica support showed greatly different adsorptions for U(VI) depending on the chemical structures of the functional group. Some resins show little or no adsorption for U(VI) from 0.1 to 6 mol/dm3 HNO3. While, resins consisting of dimethylacrylamide (DMAA) showed an increasing adsorption with an increasing concentration of HNO3 up to 9 to 12 mol/dm3. Other ions were not found to be adsorbed onto Silica-DMAA under similar solution conditions, which means that the resin is selective for U(VI) in HNO3 media.
