Abstract
To meet specification requirements, selected methods for determining uranium have been examined and two satisfactory procedures have been developed for application to the analysis of reactor-grades of hafnium, zirconium and Zircaloy-2. These procedures are based on extraction of uranyl ions from a solution of the sample with a tri- n-butyl phosphate-iso-octane mixture. Following this extraction, uranium over the range 10–150 p.p.m. is determined by a spectrophotometric method, using dibenzoylmethane. For smaller amounts of uranium, down to about 0.5 p.p.m., the determination is completed by squarewave polarography.
