COLORIMETRIC DETERMINATION OF TRACE AMOUNTS OF IRON IN URANIUM BY THE COLOR DEVELOPMENT IN THE SOLVENT LAYER. (DETERMINATION OF TRACES OF IMPURITIES IN URANIUM METAL. XV.) (in Japanese)

Journal Article · · Bunseki Kagaku (Japan)
A simplified procedure for the colorimetric determination of iron in metallic uranium was proposed. Iron in uranium chloride solution of 7.5N hydrochloric acid was extracted into butyl acetute, and the solvent layer was washed twice with 7.5N hydrochloric acid. The same volume of methyl-isobutyl- ketone was added to the solvent, and the mixed solvent layer was shaken with 20% aqueous solution of ammonium thiocyanate. The color developed in the solvent layer was measured, using a 520 m mu filter. One to 20 gamma of iron in 0.1 to lg of uranium could be determined with satisfactory results. (auth)
