摘要: 用般谱法研究了Cd(Ⅱ)-2,2′-联吡啶(bipy)、Cd(Ⅱ)-甘氨酸(Gly)二元体系及cd(Ⅱ)-bipy-Gly三元体系的配合物的形成条件,用极谱法测定了不同浓庹配体的E1/2(a)、E1/2(c)、ΔE1/2、(id)s和(id)c值,利用Lrden函数作图,外推求得各级稳定常数。

Abstract: The formation process and formation constants for binary systems Cd(Ⅱ)-2,2-bipyridyl (bipy), Cd(Ⅱ)-Glycine(Gly) and ternary system Cd(Ⅱ)-bipy-Gly were investigated by polaro-graphic method. We have also discussed the relations among various formation constants and their changeable rules.

Key words: Polarographic method, Ternary mixed-ligand complex, Stability constant
