    Description / Table of Contents: Trägerfreies 111Ag wurde aus neutronenbestrahltem Palladium ohne spezielle Reagenzien durch Kombination von Co-Kristallisation und elektrolytischer Abscheidung in mehr als 90proz. Ausbeute isoliert. Dazu wurden Messungen über die Mitkristallisation von Ag an NaCl durchgeführt sowie das Pd vor dem Bestrahlen von radiochemischen Verunreinigungen (vornehmlich Au und Ag) durch Solvensextraktion gereinigt, um ein 111Ag-Präparat hoher chemischer und radiochemischer Reinheit zu erhalten.
    Notes: Carrier free 111Ag has been separated from neutron irradiated palladium targets by the combined co-crystallisation and electrodeposition techniques. Co-crystallisation coefficient measurements of silver activity on NaCl were performed, and the best condition for the separation of Ag-111 in more than 90% yield was carried out. The method requires no consumption of special chemicals and renders the quantitative separation and subsequent use of irradiated palladium possible. The purification of target before irradiation by solvent extraction eliminates radiochemical impurities expected from trace metals in the original target, particularly gold and silver. The product separated proved to be of high chemical and radiochemical purity.
