CA 2185089

The invention relates to a process for the selective recovery of catalysts used in the production of adipic acid by (a) separating adipic acid from the reaction solution, (b) exposing the resultant reaction solution to a sulfonated ion exchanger, thereby binding iron, copper, and vanadium ions to said sulfonated ion exchanger, (c) separating the ion-exchanger from the reaction solution, (d) washing the separated ion exchanger with nitric acid to obtain an acid eluate, and (e) exposing the acid eluate to an ion exchanger modified with aminophosphonic acid groups, thereby removing the iron ions from the acid eluate.
