S>Sintered uranium dioxide pellets, ignited to U/sub 3/O/sub 8/, and uranium dioxide powder without pretreatment are dissolved in sulfuric acid in the presence of hydrogen peroxide. Boron is separated by distillation as methyl borate and determined absorptiometrically as rosocyanine. The range of the method is 0.1 to 1.5 Aicrograms boron, and, as written, is applicable to uranium dioxide powder containing 0.1 to 1.5 ppm boron and to sintered uranium dioxide pellets containing 0.02 to 0.3 ppm boron calculated on a uranium basis. Standard deviation at the 0.1 to 1 ppm levels is plus or minus 10%. (auth)
