A scheme was developed for the qualitative separation of the six platinum metals from a drop of mixture by using the ring-oven technique. Osmium( VIII), palladium(II), ruthenium(III), rhodium(III), iridium(III), and platinum(IV) were transferred one by one to the ring zone by washing, respectively, with acetic anhydride, acetone, dimethylformamide-benzene mixture (1:3 v/v), methanol, dimethylformamide, and nitric acid (0.5 N). The rings obtained were developed by Alizarin Red S (Os); 1-(2-pyridylazo)-2-napthol (Pd); acidic solution of rubeanic acid (Ru); stannous chloride --potassium iodide (Rh and Pt); and benzidine in acetic acid after fuming the paper with bromine (Ir). The time required for the separation is not more than 45 min. (auth)
