摘要： 本文研究了磷酸对伯胺N1923从硫酸溶液中萃取分离稀土(Ⅲ)与铁(Ⅲ)的影响,指出了磷酸的存在有利于稀土(Ⅲ)与铁(Ⅲ)的分离。考察了不同结构的伯胺和不同性质的溶剂及温度对萃取平衡的影响。通过IR测定和斜率法等研究,提出了N1923从磷酸介质中萃取铁(Ⅲ)的机理。
Abstract: The effect of phosphoric acid on extraction separation of rare earth(Ⅲ) and iron(Ⅲ)from sulphuric acid solution by primary amine N1923 was inve-stigated.The behavior of different primary amine and solvent or tempera-tures in dependence on the extraction seperation of rare earth(Ⅲ)was studi-ed.The mechanism of iron(Ⅲ)extraction from phosphciic acid solution was proposed.The IR study was carried out for the organic phase.
