Abstract

The cation-exchange behaviour of 43 elements in 1-24M hydrofluoric acid has been investigated by means of the radiotracer technique. Under certain conditions the alkali, alkaline-earth, rare-earth and bivalent transition metal ions are retained on Dowex-50W x 8, whereas ions forming stable anionic fluoro-complexes are not.

摘要

利用放射性示踪技术研究了43种元素在1 - 24M氢氟酸中的阳离子交换行为。在某些条件下，碱金属、碱土金属、稀土金属和二价过渡金属离子会保留在Dowex - 50W x 8上，而形成稳定阴离子氟配合物的离子则不会。
