摘要
采用乳状液膜法全分离15种单一稀土元素的系统性研究的最后两个元素钬与铒的分离在前期研究的基础上,采用P507-LMS-2-磺化煤油-HCl液膜体系,研究了各主要影响因素,在最佳实验条件下,经三级分离。
The separation of Holmium and Erbium,the last pair of individual rare earth in our systematic study on separation of rare earth elements by emulsion liquid membrane(ELM),was carried out. Based on previous work,the system of P507-LMS-2-sulfonated kerosene-HCl solution was selected and the main factors affectig the separation efficiency using this system were discussed in detail.In the optimal operation conditions,by three stages ELM processes,Er and Ho were separated with purity of 97.4% and 99.8% respectively.
