本文对HDEHP在盐酸介质中萃取轻中稀土元素的性能做了系统研究。1.测定了不同料液酸度对分配比及平衡酸度的影响。2.测定了不同浓度的有机相在不同皂化度时萃取饱和容量。3.不同料液浓度,酸度对萃取分离及各组元素之间的分离因素的影响。
In this paper, HDEHP in hydrochloric acid medium extraction of light rare earth elements in a systematic study. 1. The effect of different acidity on the distribution ratio and acidity balance was tested. Determination of different concentrations of organic phase at different saponification degree of saturation extraction capacity. The effect of different feed liquid concentration and acidity on the extraction and separation and the separation factors between the groups of elements.
