Abstract A new activity, produced by 160 MeV O16 bombardments of thick molybdenum oxide targets, is assigned to Cd103 on the basis of chemistry and its decay to Ag103. The isotope Cd103 has a half-life of10±1.5min and decays by positon emision accompanied by 0.22, 0.62 and 0.85 MeV gamma-rays.

ZusammenfassungEs wird ein Trennverfahren für Silber und die drei Platinmetalle Ruthenium, Palladium und Rhodium beschrieben, das besonders für radiochemische Untersuchungen geeignet ist. In der angegebenen Reihenfolge wird das Ag als AgCl, das Ru gelöst in Tetrachlorkohlenstoff, das Pd als Dimethylglyoximkomplex und das Rh in wäßriger Phase oder als metallisches Rh bestimmt. Die Methode liefert in der kurzen Zeit von 10–12 min eine quantitative Halbmikrotrennung dieser Elemente mit ausgezeichneter Ausbeute und hohem Reinheitsgrad.SummaryA quantitative, rapid method for the separation of silver and the three platinum metals palladium, ruthenium, and rhodium was developed for radiochemical studies and is shown to be suitable for semi-micro quantitative applications. The separation must be done in the following order: Ag is precipitated as AgCl, Ru is extracted into CCl4, Pd is precipitated as dimethylglyoxime complex, and Rh is determined either in aqueous phase or as Rh-metal. The method requires 10–12 minutes giving reproducable, quantitative separations of high chemical yield and high purity.
