| titleOfInvention | Method for dosing neptunium using absorption spectrophotometry |
| abstract | The subject of the invention is a method for assaying neptunium present in an aqueous solution by absorption spectrophotometry.n n n The aqueous solution is treated to stabilize the neptunium it contains at the degree of oxidation (V) and then the neptunium (V) is assayed by absorption spectrophotometry at a wavelength corresponding to an absorption peak for neptunium (V). The stabilization treatment consists in adding sufficient quantities of a reagent to the solution under two degrees of oxidation in order to reduce all the neptunium (VI) to neptunium (V) and to oxidize all the neptunium (IV) to neptunium ( V). The reagent is chosen so as not to exhibit significant absorption at the wavelength used for the assay of neptunium (V), for example at 981nm.n n n Preferably, a reagent based on vanadium consisting of a solution of vanadyl sulfate partially oxidized by cerium (IV) ions is used. |
