DETERMINATION OF URANIUM, ZIRCONIUM, MAGNESIUM AND IRON IN BISMUTH ALLOYS

Journal Article · · Analytica Chimica Acta (Netherlands)
Uranium in bismuth ahioys is determined by a procedure where E.D.T.A. is added to complex bismuth and other metals and uranium oxinate is extracted by chloroform and determined spectrophotometrically. Zirconium is determined spectrophotometrically using alizarin S as reagent under carefully controlled conditions of acidity and time of color formation. Magnesium is determined indirectly by measuring the absorption of oxine spectrophotometrically after precipitating the magnesium oxinate complex and redissolving. Bismuth is first separated by extraction of its iodide complex with methyl isobutyl ketone, and other interfering metals by extraction of their oxinate complexes at pH 6.5. Iron is determined as its thiocyanate complex after extraction with methyl isobutyl ketone. bismuth thiocyanate remaining in the aqueous phase. (auth)
