New titrimetric methods for palladium and platinum.
Palladium(III) is reduced to the metal by a reducing sugar in alkaline medium, and the metal is then dissolved in a solution of iron(III). The iron(II) produced is titrated oxidimetrically. Platinum is determined by precipitating it with ferrocyanide and titrating the excess of ferrocyanide added. Halides and the platinum and coinage metals interfere.
