Using oscillographic polarography, the half-wave potentials of rhodium and palladium were investigated in the presence of different ligands such as thiocyanate, pyridine, cyanide, etc. As a result of this investigation it was possible to form complexes of these metals which reduced readily at the dropping electrode, giving reduction waves which could be used quantitatively. For rhodium the thiocyanate complex was the most suitable, while for palladium the pyridine complex was best. By means of these complexes a method was developed which permits the determination of both elements in alloys, without prior separations.
