Abstract
A process for the separation of metals in which a mixture of metal derivatives is converted into anion complexes by means of a complexing anion such as, for example, a halide, thiocyanate, sulphate, nitrate, or the like said anion complexes are bound to a solid, non-soluble polymer, containing oxygen bonded to carbon which is converted into a polyoxonium compound by means of the complexing liquid medium used. The complexes are separated by selective absorption and/or elution over the polymer using suited H.sup.+ ion concentrations and/or complexing anion concentrations.
