Cyanex272与HEHEHP混合体系萃取分离重稀土的研究
Solvent Extraction and Separation of Heavy Rare Earths with Mixed Cyanex 272 and HEHEHP
【摘要】 选定了HEHEHP与Cyanex 2 72组成混合体系 ,确定了萃取体系的最佳组成 ,测定了该体系的萃取容量、反萃酸度以及相邻重稀土元素之间的分离系数 ,考察了体系萃取性能的主要影响因素。
【Abstract】 HEHEHP and Cyanex 272 were selected to form a mixed extraction system. The extraction capacity,the stripping acidity and the separation factors between each two neighboring Rare Earth elements were determined. The optimum component of the system was determined. The major elements,which affect the performance of the extraction system,were investigated.
