New Method of Rhodium Electrodissolution with High Dissolution Rate

The present paper discusses development of a high current density (2 A.cmʹ2) electrodissolution system of Rh metal that allows the solubilisation of rhodium fragments, powder and pieces of foils and wires in the presence of hydrochloric. A cylindrical, graphite centrifugal electrodissolution mini-reactor was prepared. Feeding 12 N hydrochloric acid into the system operated at 85° C and 3000 rpm rotation speed and applying a 30 amperes ac-current.
