The methods used to prepare a pure sample of diethylenetriamine-N, N, N[superscript]', N[superscript]''-tetraacetic acid-N[superscript]''-propionic acid (DTTAP) are reported;The evaluation of the protonation constants of DTTAP and of the stability constants of its anion-lanthanide complexes is also reported;The stability constant data provide information about the nature of chelation of the trivalent lanthanide ions with polyaminopolycarboxylate ligands;This new ligand shows promise as a chelating agent that can assist in the successful separation of trivalent actinides from the trivalent lanthanides. A successful Ln/An separation is necessary for the effective disposal of high-level radioactive wastes that contain the transuranic actinide elements.
