| 摘要: 用pH电位法在25℃,离子强度为0.1(KNO3)条件下研究了铀酰离子和六种2,3-二羟基-5-甲氧羰基苄基胺羧酰胺螯合剂、五种在人体血液中含量最高的小分子配体的三元配位反应,得到混配配合物的生成常数,讨论了其稳定性。通过分布计算说明促排过程中可能形成铀酰离子的混配配合物。 |

| Abstract: he ternary complexation of uranyl with sir 2,3-dihydroxy-5-carbomethoxybenzyl aminocarboxylic acid amide chelating agents and five low molecular weight ligands in biological systems have been investigated by potentiometric titration at 25℃ and an ionic strength of 0.1(KNO3). Formation constants of the mixed ligand chelates were calculated and the stability comparison were made. The presence of the mixed ligand complexes were confirmed by UV spectra. Results of computation for species distribution imply that mixed ligand complexes of uranyl may be form during decorporation. |
| Keywords: potentiometric titration uranyl aminocarboxylic acid amide chelating agent low molecular weight ligand mixed ligand complex |
