摘要
水溶性高聚物的水溶液在无机盐存在下能分成两相,文献提出了用其分离金属离子的可能性。作者在前文中,系统研究了聚乙二醇2000-盐-水体系的分相条件,用偶氮胂Ⅲ作萃取剂,实现了该体系的La(Ⅲ)-Zr(Ⅳ)定量萃取分离。非有机溶剂萃取体系,能萃取水溶性螯合物,并可用显色剂作萃取剂,使整个萃取操作具有安全、无毒害、简便,快速的特点。
In polyethylene glycol-inorganic salt-water system the liquid-liquid extraction behaviour of the complexes of copper (Ⅱ), Bismuth (M) and Zircon-ium(Ⅳ) with xylenol orange was investigated by using XO as extractant. The quantitative extraction separation of Cu(Ⅱ)-Zr(Ⅳ ), Cu(Ⅱ )-Bi(Ⅲ) and Bi(Ⅲ)-Zr(Ⅳ) based on this system was carried out by controlling the acidity of the solution and adding some masking agents. The separation results are satisfactory. The extraction machanism for the system was also studied.
