Separation of curium from americium using composite sorbents and complexing agent solutions: Part 2.
Original language description
TODGA PAN composite sorbent and (PhSO3H)2 BTPhen in nitric acid solution were employed as a system for separation of curium from americium. The influence of aqueous phase composition (complexing agent and nitric acid concentrations) on weight distribution coefficients and Cm/Am separation factor was studied in batch experiments with trace amounts of 241Am and 244Cm. Based on the results obtained, column experiment was designed and conducted. The Cm/Am separation factor of 3.8 ± 0.1 found in batch experiments with TODGA-PAN could be reproduced also in column experiment resulting in good separation of Cm from Am. The efficiency of Cm separation from Am in the TODGA-PAN system was compared with the analogous system with DGA Resin (Triskem International). After separation on a 0.5 mL column (4.7 x 29 mm) the Cm fraction containing 93 % of Cm(III) contained only 3 % of Am(III) in optimum conditions.
