| titleOfInvention | Method for separating neptunium from uranium product by TEVA-UTEVA extraction chromatographic column |
| abstract | The invention discloses a method for separating neptunium (Np) from a uranium product by a TEVA-UTEVA extraction chromatographic column. The method comprises the following steps: (1) adding an acidic solution and a reducing agent into the uranium product to stabilize the neptunium into Np (IV), separating the neptunium from the uranium by a TEVA levextrel resin, and desorbing the neptunium by the mixed solution of nitric acid and oxalic acid; and (2) allowing the eluent to pass through a UTEVA extraction chromatographic column to further purify the neptunium. According to the method provided by the invention, the two separation processes only need one-time price adjustment and are simple; the method is high in recovery rate, precision and separation efficiency and stable in recovery; and the neptunium is separated from the uranium product with the ratio of the uranium to the neptunium of 106:1 by the TEVA-UTEVA extraction chromatographic column. |
