摘　　要：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.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.
