Separation of curium and americium traces by displacement complexing chromatography in the presence of separating ions: 2. Influence of the amount ofcadmium ions and modes of their introduction in the system on the efficiency of separation of curium and americium

The efficiency of separation of curium and americium by elution with a nitr ilotriacetic acid solution was studied as influenced by the amount of cadmi um separating ions and the mode of their introduction in the system. Separa te sorption of curium, americium, and cadmium, as compared to their cosorpt ion, increases the completeness of separation of curium and americium. The efficiency of the separation increases with increasing amount of cadmium in troduced into the system and is independent of the elution rate.
