Cation-exchange of 43 elements from hydrofluoric acid solution.
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.
