PROCESSO PARA A RECUPERACAO DE RODIO

摘要

For the recovery of the rhodium contained in them as soluble compounds, the distillation residues of products of the oxo synthesis are treated with oxygen or an oxygen-containing gas in the presence of an alkali metal salt of a C2- to C5-monocarboxylic acid. The noble metal is then extracted from the organic phase using the aqueous solution of a complex-forming reagent, optionally after it has already been previously extracted with water on its own.
