Abstract
Palladium may be precipitated quantitatively with 1,10-phenanthroline from palladous chloride solutions; variations in the hydrochloric acid concentration from 1 to 20% had no effect on the precipitation. The reagent yields no precipitates with other platinum metals under similar conditions; slightly high results, however, were obtained when palladium was precipitated from solutions containing these metals. The precipitate has the composition C12H8N2PdCl2 and may be used as a weighing form for palladium. A micro-volumetric method for palladium using 1,10-phenanthroline is described. Small amounts of platinum (as Pt+4) do not interfere.
