Summary
An electromigration technique was used for measurements of metal-ligand formation constants of non-carrier-free 160Tb3+ with glycolate, D-gluconate and α-isosaccharinate ligands. The overall ion mobilities of Tb at different concentrations of the ligands were measured in chemically inert perchlorate solutions (pH 7 and T= 298.1K) with an overall ionic strength μ = 0.1. The stepwise stoichiometric stability constants are: Tb3+/glycolate: log K1=2.72(18), log K2=1.73(19), log K3= 1.12(17), Tb3+/D-gluconate: log K1=2.96(11), log K2=2.60(11), log K3=1.13(9), Tb3+/α-ISA: log K1=3.07(8), log K2 = 2.69(11), log K3 = 1.80(12).
