Rare-earth separation based on the differences of ionic magnetic moment via quasi-liquid strategy
文献摘要：
The separation of rare earth elements is particularly difficult due to their similar physicochemical properties.Based on the tiny differences of ionic radius,solvent extraction has been developed as the"mass method"in industry with hundreds of stages,extremely intensive chemical consumption and large capital investments.The differences of the ionic magnetic moment among rare earths are greater than that of ionic radius.Herein,a novel method based on the large ionic magnetic moment differences of rare earth elements was proposed to promote the separation efficiency.Rare earths were firstly dissolved in the ionic liquid,then the ordering degree of them was improved with the Z-bond effect,and finally the magnetic moment differences between paramagnetic and diamagnetic rare earths in quasi-liquid system were enhanced.Taking the separation of Er/Y,Ho/Y and Er/Ho as examples,the results showed that Er(Ⅲ)and Ho(Ⅲ)containing ionic liquids had obvious magnetic response,while ionic liquids containing Y(Ⅲ)had no response.The separation factors of Er/Y and Ho/Y were achieved at 9.0 and 28.82,respectively.Magnetic separation via quasi-liquid system strategy provides a possibility of the novel,green,and efficient method for rare earth separation.
