Abstract A. circular-paper Chromatographie method for separating the precious metals Pd +2 , Pt +4 , l r+4 . Rh +3 , Ru +3 , Os +4 and Au +3 , using several solvent mixtures with or without complexing agents, has been studied. Mixtures of microamounts of three or four of these metals can be effectively separated into distinct circular zones within one or two hours.
