The stability constants of ternary complexes of Gd(Ⅲ) with citric(L-aspartic) acid and L-serine(L-threonine) under the synthetic biological conditions of temperature and background electrolyte (37℃, 0.15 mol/L NaCl) were obtained by potentiometric titration. The distributions of Gd(Ⅲ) species in these systems have been discussed.
