Technology Process of (~237~Np)neptunium dihydrate

There total 1 articles about (~237~Np)neptunium dihydrate which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

(237)neptunium + oxygen (80937-33-3) → (237)neptunium dioxide (58670-16-9,12035-79-9)

Guidance literature:

In not given; triple electrorefined (237)Np oxidize by air;

DOI:10.1002/ejic.201100464

Reference yield:

(237)neptunium dioxide (58670-16-9,12035-79-9) → neptunium(V) (86954-34-9)

Guidance literature:

With potassium bromate; nitric acid; sodium nitrite; In nitric acid; The NpO2 is dissolved in concd. HNO3 with heating, soln. is diluted with water and heated in presence of KBrO3 for 1 h, soln. is once more diluted with water and HNO3 and NaNO2 are added.; Addn. of ammonia, ppt. is washed with water and dissolved in HNO3, concentration of Np((V) is determined spectrophotometrically and radiomtrically.;
