摘要
在稀盐酸的介质中，锌（Ⅱ）与硫氰酸盐络合形成硫氰酸合锌络阴离子，用正丁醇萃取锌络合物，把锌（Ⅱ）反萃于水中，在PH值为5－6的条件下，用EDTA标准溶液滴定锌。
Zinc (Ⅱ ) compounds with thiocyanate in the thin hydrochloric acid, forming thiocyanato - Zinc (Ⅱ ) ion. Zinc complex compound is extracted by n - butyl alcohol and Zinc (Ⅱ ) is counter - extracted into water. Zinc is titrated by using EDTA standard solution at PH 5 - 6.
