摘要
研究了硫酸铵－水杨基荧光酮－乙醇体系萃取钼的行为及乙醇水溶液的分相条件。试验表明，作为萃取溶剂的乙醇，能萃取电中性螯合物又能萃取带电荷螯合物，当溶液ｐＨ １～２，能使Ｍｏ（Ⅵ）与Ｆｅ（Ⅲ）、Ｃｕ（Ⅱ）、Ｃｏ（Ⅱ）、Ｍｎ（Ⅱ）分离。
The extraction behaviour of (NH4)2SO4-salicylfluorone-Ethanol system was stud- ied and proper conditions were selected. It shows that Mo(Ⅵ) can be completely separated from Fe(Ⅲ), Cu(Ⅱ), Mn(Ⅱ), Co(Ⅱ), Ni(Ⅱ) by adding 3.5 g (NH4)2SO4 to 10 mL 30% (V/V) ethanol solution at pH= l-2.
