Polystirene and acrylic acid resins loaded with dibuthyl-N,N-diethyl-carbamyl phosphonate (DBDECP) and dihexyl-N,N-diethyl-carbamylmethylene phosphonate (DHDECMP) were used for liquid-solid extraction of 224-Cm. The uptake of the metal ion was evaluated as a function of HNO3 or HCl concentrations. Quantitative recovery of 224-Cm was obtained from HNO3 for all resins loaded with DBDECP both in static and dynamic experiments. The results obtained with the different ligands, resins and experimental conditions are discussed

Abstract
Polystirene and acrylic acid resins loaded with dibuthyl-N,N-diethyl-carbamyl phosphonate (DBDECP) and dihexyl-N,N-diethyl-carbamylmethylene phosphonate (DHDECMP) were used for liquid-solid extraction of 224-Cm. The uptake of the metal ion was evaluated as a function of HNO3 or HCl concentrations. Quantitative recovery of 224-Cm was obtained from HNO3 for all resins loaded with DBDECP both in static and dynamic experiments. The results obtained with the different ligands, resins and experimental conditions are discussed
