摘要:
1. IN A METHOD FOR RECOVERING PALLADIUM, TECHNETIUM, AND RHODIUM AND RUTHENIUM VALUES FROM AN AQUEOUS ACID FEED SOLUTION CONTAINING THESE AND OTHER VALUES AND FROM EACH OTHER COMPRISING: CONTACTING THE FEED SOLUTION WITH A FIRST BED OF CARBON, SAID BED HAVING ABSORBED THEREON DIMETHYLGLYOXIME, WHEREBY ONLY THE PALLADIUM IS CHELATED AND IS RETAINED ON THE FIRST BED, CONTACTING THE FEED SOLUTION WITH A SECOND BED OF CARBON, SAID SECOND BED HAVING ADSORBED THEREON A CHELATING AGENT SELECTED FROM THE GROUP CONSISTING OF DIACETYL DITHIOL AND DIACETYLTOLUENE-3,4-DITIOL, WHEREBY ONLY TECHNETIUM IS CHELATED AND REMAINS ON THE BED, CONTACTING THE FEED SOLUTION WITH A THIRD BED OF CARBON, SAID BED HAVING ADSORBED THEREON A CHELATING AGENT SELECTED FROM THE GROUP CONSISTING OF 8-MERCAPTOQUINOLINE AND PHENYLTHIOUREA, WHEREBY ONLY THE RHODIUM AND RUTHENIUM ARE CHELATED AND REMAIN ON THE BED, AND RECOVERING THE VALUES FROM THE CARBON BEDS.
