Determination of a trace of manganese contained in uranium metal has been made by the spectrophotometric method with permanganate. The sample is dissolved in hydrochloric acid and excess nitric acid. Hydrochloric acid is removed by evaporation. Urarium is separated from a nitric acid (4N to 6N) solution with TBP--CCl/sub 4/. Sulfuric acid is added, and the solution is heated to fume; water, silver nitrate, and ammonium persulfate solution are added and boiled. Manganese in the sample solution is oxidized to permanganate. The color of permangaanate is measured by the light transmittancy at 525 m mu . When 2 g of the sample is taken and the volume of permanganate solution is made up to 10 ml, as low as 2 ppm manganese in uranium metal can be detemnined. (auth)
