Abstract: The present invention is related to a method and apparatuses for the electrodissolution of an element, in particular of fragments of an irradiated metallic target, comprising a fraction of a radio-isotope, for example Palladium-103. Besides the known steps of subjecting an electrolytic solution comprising the fragments to a voltage applied between two electrodes submerged in the solution, the method comprises the step of applying an external force to the solution in order to accumulate the fragments in the vicinity of one electrode, and thereby accelerate the dissolution process. The force applied may be centrifugal, or it may be a force obtained through a flow of the solution.
