RECOVERY OF PALLADIUM FROM RINSE WATER

摘要

A process for the essentially total removal of palladium cations in a cation exchange resin bed, followed by removal of chloride and palladium chloride anions in an anion exchange bed. Recovery of the precious metal is effected by mixing the solutions used to regenerate the ion-exchange beds in such proportion as to maintain a pH of less than 6 for the mixture, then adding a reducing agent to the precipitate palladium to the substantial exclusion of all other metals.
