Process for the separation of rhodium from organic solutions

摘要

A process for the separation of rhodium from rhodium containing organic solutions, organic-aqueous mixtures or aqueous solutions containing complexing agents is disclosed. Metallic bismuth, bismuth oxide, bismuth hydroxide or another reducible bismuth compound is added to 50 DEG to 250 DEG C. as a precipitating agent, optionally with a reducing agent, and the precipitate is separated. The corresponding antimony compounds can also be used in place of bismuth.
