Isolation of osmium and ruthenium by ionexchange paper and subsequent determination by X-ray fluorescence.
Quantitative separations of microgram quantities of osmium and ruthenium from large proportions of copper, iron and nickel were accomplished by the use of anion-exchange paper. Accurate determinations of osmium and ruthenium were made by adaptation of X-ray fluorescence. Wet methods for the dissolution of the paper and exchanger and subsequent wet determinations of osmium and ruthenium are discussed.
