| SPECIESOF Tb(Ⅲ) AND Ca(Ⅱ) IN THE PRESENCE OF L-GL UTAMIC ACID AND GLYCINE | |
| 摘要: 在模拟生理条件下(37℃,I=0.15mol/LNaCl),用pH电位法研究了铽(Ⅲ)、钙(Ⅱ)与L-谷氨酸、甘氨酸二元、三元体系。确定了体系存在的物种,测定了体系中配合物的稳定常数。讨论了上述二元、三元体系中铽(Ⅲ)、钙(Ⅱ)的物种分布特点。 | |

| Abstract: Tb(Ⅲ)-Glu(Gly),Ca(Ⅱ)-Glu(Gly),Tb(Ⅲ)-Glu-Gly and Ca(Ⅱ)-Glu-Gly systems were studied by potentiometric titration under the physiological condition.The species of Tb (Ⅲ) and Ca(Ⅱ) were ascertained,and the stability constants of the complexes in these systemswere determined.The distribution of speciesof Tb(Ⅲ) and Ca(Ⅱ) wasdiscussed. | |
