Procedures are described for the analysis of bismuth-base alloys containing 0.2 to 5% of uranium and 0.2 to 5% of neodymium or praseodymium. Bismuth is first separated from a solution of the alloy in 1 N nitric acid by extraction with diethylammonium diethyldithiocarbamate in chloroform, followed by the separation of uranium with the same reagent from an acetate buffered solution of pH 5.5 to 6.0. The uranium determination is completed by measuring the absorbancy of its diethyl ABSTRACTS dithiocarbamate complex in chloroform. The neodymium or praseodymium is determined by titration with EDTA of the aqueous solution remnining after the separation of bismuth and uranium, using xylenol orange indicator in solutions of pH 5.6 to 5.8. EDTA is also used to determine the bismuth by direct titration of a separate aliquot of the sample solutions. (auth)
