Selective uranium adsorption using modified acrylamide resins

Polymeric matrices composed of N,N′-Methylenebis(acrylamide)/glycidyl methacrylate was prepared and modified producing two resins (GMA/MBA/OH and GMA/MBA/SO₃H). The adsorption of U(VI) ions onto the modified acrylamide resins was studied from synthetic and granite samples. For better understanding around the uranium mineralization and the rock-forming minerals of the hosted granitic rocks, to facilitate the choice of the appropriate ore-processing techniques, it was necessary to identify the mineral composition and the radiometric specifications of the used granitic rock. The synthesized adsorbents revealed a promising selective adsorption toward the U(VI) ions from its bearing solutions even with the competence of other cations.
