摘要
以氢离子选择性电极作指示电极,氢氧化钠溶液作滴定剂,用半整数生成函数法分别测定了谷氨酸合铜、谷氨酸合镍及谷氨酸合锌的各级条件稳定常数。除谷氨酸合锌的第3级稳定常数,其他测定结果与文献值吻合。
Bjerrum＇s half-integer formation function method was applied to the determination of the stability constants of three glutamic acid-nickel and glutamic acid-zinc. H and sodium hydrate was used as the acid-metal ion complexes, including glutam ydrogen ion selective electrode was used as t titrant. All the measurement results agreed values except for the third level stability constant of glutamic acid-zinc complex. ic acid-copper, glutamic he indicating electrode, well with the literature
