In sulfuric acid solution, manganous ion is quantithtively oxidized to permanganate ion by alkali periodates. The permanganate color, which is stable in the presence of excess periodate, exhibits an absorbance maximum at 525 mu. The interference of residual or alloying iron, chromium, and nickel is elimthated by discharging the permanganate color in a portion of the sample solution with sodium azide and using this solution as a blank. The method covers the determination of manganese as an impurity in zirconium and Zircalioy in the range of l0 to 200 ppm on the basis of a one gram sample. (auth)
