Spectrophotometric Determination of Traces of Boron in Uranium

Procedure is described for the spectrophoto-metric determination of 0.1∼1 p.p.m. of boron in uranium (metal, U3O8, and uranyl sulfate). Uranium metal was first converted to U3O8, and the oxide was dissolved in sulfuric acid and hydrogen peroxide. Boron was separated by distillation as methyl borate...

Summary:Procedure is described for the spectrophoto-metric determination of 0.1∼1 p.p.m. of boron in uranium (metal, U3O8, and uranyl sulfate). Uranium metal was first converted to U3O8, and the oxide was dissolved in sulfuric acid and hydrogen peroxide. Boron was separated by distillation as methyl borate from sulfuric acid solution, and finally determined by the curcumin method.
