Book Description
The best methods at the present time for separating neptunium from various types of source material are outlined. For the purpose of analytical classification neptunium may be grouped with uranium and plutonium since all three elements, mixed in an aqueous solution, can be oxidized to a characteristic +6 state. An excellent separation from other metal ions is obtained by extraction of the +6 states into diethyl either. Methyl isobutyl ketone is also an effective extracting solvent although it is not as specific. All three elements in the +6 state will precipitate with sodium as double acetates of the formul NaXO2 (OOCCH3)3. Neptunium may be separated from uranium and plutonium by solvent extraction and precipitation. Np(IV) forms a benzene soluble, chelate complex with thenoyl trifluoroacetone. Under suitable reducing conditions Np(IV) can be extracted away from Pu(III) and U(VI). A separation method involving the precipitation of fluorides is essentially dependent on the relative rates of oxidation and reduction of uranium, neptunium, and plutonium.

Book Description
This report presents some procedures used in the radiochemical isolation, purification and/or analysis of uranium, neptunium, and plutonium. In this update of the procedures, we have not attempted to discuss the developments in the chemistry of U, Np, and Pu but have restricted the report to the newer procedures, most of which have resulted from the increased emphasis in environmental concern which requires analysis of extremely small amounts of the actinide element in quite complex matrices. The final section of this report describes several schemes for isolation of actinides by oxidation state.
