Abstract
Process for recovering palladium, rhodium and ruthenium from aqueous solutions deriving from the processing of nuclear fuel, also containing iron and nickel, by reductive carbonylation with carbon monoxide at a pressure lying between 0 and 1 atmosphere in nitric acid solution at a pH lying between 2 and 4 at a temperature lying between ambient and 100 degree C and with reaction times lying between 6 and 100 hours.
