[中文文摘]本工作用电位法研究溶液中Zn(Ⅱ)混合配体络合物的形成。实验结果表明,在氢氧化钠-三乙醇胺溶液中,Zn(Ⅱ)的主要络合品种为Zn(TEA)(OH)_2。在氢氧化钠-乙二胺四乙酸溶液中Zn(Ⅱ)的主要络合品种为[Zn(EDTA)(OH)_2]~(4-)。[英文文摘]Formation of mixed ligand complexes of Zn(II) was studied by means of potentiomctric determination. The experimental results show that the predominant complex species in NaOH-TEA solutions is Zn(TEA)(OH)2, and in NaOH-EDTA solutions-[Zn(ETDA)(OH)2]4-
