Notes:
Diethylenetriamine-pentaacetic acid (DTPA) forms with metal cations Mv+ the complexes MZv-5; MHZv-4, M2Z2v-5, where Z5- stands for the anion of DTPA. Complexes MM′Zv1 + V2 -5 containing two different metals are also formed. The stability constants of these species with Ca, Mn, FeII, FeIII, Co, Ni, Cu, Zn, Cd, Pb, Hg, Ce have been determined, using 7 methods. The DTPA-complexes are considerably more stable than the corresponding EDTA-complexes which makes DTPA a considerably better titrant in complexometry.
