摘要
研究了在碱性条件下吐温 80与几种盐的分相关系 ,探讨了盐浓度、碱度对螯合剂和金属离子螯合物萃取率的影响 .在最佳分离条件下 ,实现了 Co(II) - Zn(II) ,Ni(II) - Zn(II)
In the presence of some salts and different alkaline medium, Tween 80 can be separated into solid phases from the liquid phases.The effect of concentration basicity on the percentage of extraction for chelating agent and metal chelates was studied.The quantitative extraction and separation of Co(II) Zn(II), Ni(II) Zn(II) were carried out with the most appropiate separation condition.
