Popis: This study was undertaken to develop a means of determining oxygen in zirconium which is present in a form other than that of zirconium oxide. The method described determines oxygen which is evolved as molecular oxygen when solid zirconium metal is dissolved in hydrofluoric acid solution. The oxygen evolved is caught in a separate flask and ultimately determined colorimetrically as iodine. In this procedure, the oxygen held as ZrO/sub 2/ is not evolved and is not determined. Thc range of oxygen determined by this method was between 50 to 170 mu g which is equivalent to 0.06 to 0.22% oxygen. The deviation was plus or minus 0.01% oxygen. (auth)
