PROCESS FOR THE RECOVERY OF RHODIUM FROM AQUEOUS SOLUTIONS CONTAINING RHODIUM COMPLEXES

A process for the recovery of rhodium from aqueous solutions of complexes thereof wherein the solutions are treated with oxygen in the presence of a water salt of a carboxylic acid and, in a second stage, further treated with a hypochlorite, whereby oil soluble rhodium compounds are formed which can...

Beschreibung
Zusammenfassung:	A process for the recovery of rhodium from aqueous solutions of complexes thereof wherein the solutions are treated with oxygen in the presence of a water salt of a carboxylic acid and, in a second stage, further treated with a hypochlorite, whereby oil soluble rhodium compounds are formed which can readily be separated from the aqueous solution.
