| Abstract: | Sequential separation of the trivalent actinides Cm and Cf is investigated by extraction chromatography using the system Alamine 336-LiCl on the diatomaceous earth, Celite 360. The effect of the mobile phase concentration and the acidity on the distribution behaviour of both elements is found almost to parallel that based on simple liquid-liquid extraction. Optimum resolution and efficient decontamination is readily achieved by 11 M LiCl in 0.02 M HC1. The possible use of the same system for the decontamination of the +3 actinides from various foreign ions is also pointed out. |
