PROCESS FOR SEPARATING AND RECUPERATING SOLID COMPLEXES OF NOBLE METALS OF THE VIII GROUP

摘要

A method for the recovery of a Group VIII noble metal solid complex is described, which comprises bringing an organic compound-containing solution containing therein a Group VIII noble metal complex having a tertiary organophosphorous compound as a ligand into contact with an oxidizing agent in the presence of a free tertiary organophosphorous compound, an organic polar solvent, water, and a basic substance to preciptate a solid complex of the Group VIII noble metal, and a separating the precipitated Group VIII noble metal solid complex from the solution.
