Elbling, P; Goward, G W

The metal sample is reacted with carbon in molten platinum in a graphite crucible. Carbon reacts with the oxides in the sample to form carbon monoxide, which is swept out of the reaction tube with a stream of purified argon. Iodine pentoxide oxidizes the carbon monoxide to carbon dioxide, which is absorbed by a dilute sodium hydroxide solution. The amount of oxygen present in the sample is determined by measuring the change in conductance of the absorbing solution and comparing this change against that of a standard curve prepared by the analysis of known amounts of stoichiometric metal oxides such as silver, uranium, niobium, or zirconium oxides. The method covers the determination of oxygen in zirconium and Zircaloy. The range is from 50 ppm (1 g sample) to 7000 ppm (0.1 g sample). (auth)
