摘要
介绍了近年来镅等锕系元素与镧系元素的分离研究进展,其中发展较快的膜分离技术主要适用于低浓度废液,萃取法因为其自身的优点已经成为研究最多的方法。开发一种萃取效果好,成本低,可用于大规模工艺流程的新型萃取剂已经成为萃取分离的重点研究方向。
The development of the separation method from actinium and lanthanide in recent years is introduced. Membrane separation technique is developing very fast, which is mainly used in the separation of the low concentration waste liquid, and the extraction technique is becoming the method studied most because of its several obvious advantages. To develop a new kind of extraction reagent with low cost and good separation affectivities is the key research field at present.
