ANALYTICAL METHOD FOR THE ABSORPTIOMETRIC DETERMINATION OF BORON IN URANIUM DIOXIDE POWDER AND SINTERED URANIUM DIOXIDE PELLETS

Technical Report · Sun Jan 01 00:00:00 EST 1961

OSTI ID:4832888

Sintered uranium dioxide pellets, ignited to U/sub 3/O/sub 8/, and uranium dioxide powder without pretreatment are dmssolved 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 l.5 micrograms boron, and 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 (95% confidence limits) at the 0.1 to 1 ppm levels is plus or minus 10%. (auth)
