Abstract

Chromatographic paper treated with a liquid anion exchanger (tri- n-octylamine) behaves like an anionic resin film; consequently many separations of cations that form anionic complexes can also be carried out by means of this new chromatographic procedure. Many examples are reported, among which the separation of the very similar elements zirconium and hafnium is of great significance. It is anticipated that it will be possible to isolate traces of complexed metals from large quantities of non-complexed elements.
