The enthalpies of formation of the 1:1 complexes of Am(III) with acetate an a series of amino carboxylate ligands were determined by titration calorimetry. The estimated {Delta}H{sub 101} values are -6.8, 4.5, 12.6, 23.9, 10.8, 39.5, and -13.3 kJ mol{sup {minus}1} for complexation by acetate, IDA, NTA, EDTA, DCTA, DTPA, and TMDTA, respectively. Comparison of these values with those for the Eu(III) and Cm(III) complexation provides no evidence of significant differences in the bonding of these three metal ions with the ligands studied. 13 refs., 3 figs., 3 tabs.
