A simple, precise and quick potentiometric method for the determination of Ru(lIl) from 84.00 ~ to 3.35 mg in a total volum\? of 70.0 ml with a maximum relative standard deviation of 0.7% . using Co(lll) acetate as redox titrant has been devised. Interference effects of foreign ions on this determination have also been investigated.
