摘要: Tb(Ⅲ) and Ca(Ⅱ) ion equilibria in the presence of glutamic acid and glutamine were studied by potentiometric titration at 37℃ and an ionic strength of 0.15mol/L(NaCl).The stability constants for Tb(Ⅲ) and Ca(Ⅱ) complexes in the systems were obtained.The species and their distribution in the systems were discussed.
