Separation of trivalent lanthanides and actinides by solvent extraction without aqueous complexing agents
Description: A method of separating the trivalent actinides, mainly Am and Cm, from trivalent lanthanides is presented. This method embodies the sequential use of two different solvent extractants; the first extractant would remove the heavy lanthanides from the lighter lanthanides and Am--Cm, while the second would extract Am--Cm in preference to the lighter lanthanides. In this scheme, no additional complexing agents are required. Thus, waste disposal and corrosion problems are minimized. Overall separation factors for Am--Cm from lanthanide fission products in reactor wastes may be as high as several thousand. (auth)
