本文用pH法测定了Cd(Ⅱ)与邻氨基苯甲酸在15、25、35和45℃,离子强度为0.10(KNO_3)条件下的一、二级配合物稳定常数。从配体、配合物的结构,以及热力学函数的角度对配合物的稳定性进行了讨论。
In this paper, the stability constants of primary and secondary complexes of Cd (Ⅱ) with anthranilic acid at 15, 25, 35 and 45 ℃ and ionic strength of 0.10 (KNO 3) were determined by pH method. The stability of the complex was discussed from the viewpoints of ligand, structure of the complex and thermodynamic function.
