Abstract
INCREASING the number of donor groups in chelating agents can give rise to the formation of more stable chelates1–3 and, therefore, to a higher mobilization of internally deposited trivalent and other metal ions of higher valency. This has been demonstrated with ethylenediamine - NNN′N′ - tetraacetic acid (EDTA) and diethylenetriamine-NNN′N′N″-penta-acetic acid (DTPA)4,5, that is, with chelating agents with 6 and 8 donor groups respectively. For this reason extension of this work to the 10-dentate triethylenetetraamine - NNN′ N′ N″ N‴ - hexaacetic acid (TTHA) seemed to be worth while.
