Preparation and uranyl sorption of extractant resin containing ammonium groups

Summary An extractant resin was synthesized by radical polymerization of 3-(methacryloyl amino)propyl] trimethyl ammonium chloride in presence of N,N-methylene-bis-methacrylamide as crosslinker agent at different concentrations. All the resins are insoluble in water. The resins showed high affinity and selectivity for uranium. The resins do not retain significantly copper (<6%). Elution assays with sulfuric acid and sodium carbonate, were also carried out.
