PROCESS FOR RECOVERING RHODIUM

摘要

A process for recovering rhodium from an aqueous solution containing its complex compounds and optionally complex ligands in the presence of a water-soluble salt of a carboxylic acid by treatment of the aqueous solution at 20 DEG to 120 DEG C. with hydrogen peroxide (or a substance forming hydrogen peroxide) and with oxygen (or an oxygen-containing gas). The rhodium is then removed as a water-insoluble compound.
