Cu（Ⅱ）－正已（辛）烷基亚氨二乙酸－DL－天冬酸、L－谷氨酸体系混配型配合物的研究

Study on Mixed Ligand Coordination Compounds of Cu(Ⅱ)-n-alkyl(hexyl or octyl) Iminodiacetate-DL-Aspartic acid or L-Glutamic Acid

用ｐＨ电位法研究了Ｃｕ（Ⅱ）－正已（辛）烷基亚氨二乙酸（Ｈ２Ａ）ＤＬ－天冬酸、Ｌ－谷氨酸（统以Ｈ２Ｂ表示）体系的混配型配合物。在２５±０．１℃，μ＝０．１（ＫＮＯ３）的条件下，测定了该体系的混配型配合物的稳定常数。

The stability Constant of complexes formed by n-alkyl(hexyl or octyl) iminodiacetate-DL-Aspartic acid or L-Glutamic acid with Cu(Ⅱ) has been determined pH-potentiometrically at 25±0.1 and the apparent ionic strength 0.1 (KNO3) both in aqueous solution.
