摘要
报道了测定镀铜-锌合金溶液中的铜、锌的一种简易、快速螯合滴定法。方法是用ED-TA螯舍铜(Ⅱ)、锌(Ⅱ)和其它金属离子,然后分别用巯基乙酸(TGA)和邻菲罗啉(phen)解蔽。研究了在测定铜、锌时一般共存离子的干扰。此法已被用于镀铜-锌合金溶液中的铜、锌的测定。
A simple chelatometry method for the determination of Cu and Zn in Cu-Zn alloy plating solution is presented. It is based on the initial chelation of Cu ( Ⅱ ) and Zn ( Ⅱ) with EDTA and its subsequent decomposition with phen and thioglycollic acid. Interference of ions normally encountered in determination was also studied.
