| 摘要: 本文应用pH-电位法在T=25.0±0.1℃,I=0.5mol·l-1KNO3下测定了Cu2+与甘氨酸(glyH2),β-丙氨酸(β-alaH2),丙二酸(prodH2)和丁二酸(butadH2)等配体形成的配合稳定常数。简要分析了△logK值偏正的原因可能是分子内配体基团之间的相互作用。 |

| Abstract: The stability constants of binary and ternary complexes of different types ML, ML2, MLH, MLL',where M = Cu2+, L(L') = glycine, β-alanine, malonic acid and butanedioic acid, have been determined by pH potentiometric titration in aqueous solution (I = 0.5 mol·1-1 KNO3, T = 25℃). On the basis of the program TITFIT and our former work, we have made a TRI-TITFIT program to calculate the stability constants of ternary complexes. The stability of ternary complexes was discussed considering the ligand-ligand interaction. |
