本文较系统地研究了弱碱性杂环胺二啮配体邻菲绕啉1,10-Phenanthrolion(Phen)和α-羟基异丁酸Hydroxy-iosbutyric acid(HHIBA)混合体系对稀土元素(RE~(3+))的萃取。此体系和RE-Phen-Sal混合体系相似,也存在明显的“四分组效应”,但萃取率要低得多。萃合物的组成为[RE(Phen)(HIBA)Cl_2(H_2O)_2]。此外,关于邻菲绕啉和α-羟基异丁酸在硫氰酸盐介质中对稀土元素的萃取性能,我们也进行了一些研究,发现邻菲绕啉与α-羟基异丁酸对稀土元素的萃取存在着协同效应。
In this paper, we systematically studied the effect of rare earth elements (RE ~ (Ⅱ)) mixed with 1,10-Phenanthrolion (Phen) and Hydroxy-iosbutyric acid (HHIBA) (3+)). This system is similar to the RE-Phen-Sal mixed system with a clear “quadrant effect”, but at a much lower extraction rate. The composition of the complex is [RE (Phen) (HIBA) Cl_2 (H_2O) _2]. In addition, on the phenanthroline and α-hydroxyisobutyric acid in the thiocyanate medium rare earth elements extraction performance, we also conducted some research and found that phenanthroline and α-hydroxyisobutyric acid on rare earth elements There is a synergistic effect of extraction.
