THE DETERMINATION OF IRON IN URANIUM BEARING MATERIALS BY USE OF AN ETHYL ACETATE EXTRACTION AND A COLORIMETRIC BATHOPHENANTHROLINE PROCEDURE
Ferrous iron forms a colored complex with 4, 7diphenyl-1, 10- phenanthroline (bathophenanthroline) which was made the basis of a colorimetric method for the determination of microgram amounts of iron in material of varying uranium content. Of the commonly occurring elements, the only interfering element found was copper. The effect of this contaminant was eliminated by extracting the iron by means of ethyl acetate from a solution strongly acid in hydrochloric acid. The efficiency of this ethyl acetate extraction procedure was investigated and its use as a substitute for longer and more involved separations is illustrated. A preliminary investigation was carried out on the application of the bathophenanthroline method to the direct determination of ferrous iron on typical mill solutions. (auth)
