This report describes the adaptation of a colorimetric method, using curcumin as colorimetric reagent, to the determination of boron in uranium metal and some of its compounds. A feature of the method is a new method of dissolution of the oxides of uranium in sulphuric acid and potassium dichromate which avoids complications, such as incomplete recovery of boron in the distillation step, and reduces the introduction of extraneous boron from the reagents. The metal is converted to the oxide in the distillation apparatus in order to prevent losses of boron and the resulting oxide is dissolved in sulphuric acid and potassium dichromate. The method proposed for uranyl nitrate involves the reduction of nitrate by boiling under reflux with hydrazine sulphate in sulphuric acid solution. Good recoveries of boron are obtained by these procedures.

Download Ultraviolet Spectrophotometric Determination of Uranium Book in PDF, ePub and Kindle
An ultraviolet spectrophotometric method for the determination of uranium has been developed which is based on the ultraviolet absorption of the complex of uranium(VI) with tris-(2-ethylhexyl)phosphine oxide. The complex is formed by extracting uranium(VI) from an aqueous 6M sodium nitrate solution in the pH range 2.5-3.0 into 0.1M solution of tris-(2-ethylhexyl)phosphine oxide (TEHPO) in an inert diluent, cyclohexane.
