| titleOfInvention | Method for separating element palladium and sub-actinide elements from high-level waste |
| abstract | The invention discloses a method for separating element palladium from high-level waste, which includes the steps: adding concentrated nitric acid into nitrate solution of the high-level waste to adjust the nitric acid concentration to be 2mol/L; and allowing the high-level waste nitrate solution with the nitric acid concentration adjusted to pass through a chromatographic column filled with adsorbent to enable element palladium and sub-actinide elements to be adsorbed by the chromatographic column filled with the adsorbent; using nitric acid aqueous solution of thiourea to elute the chromatographic column with the adsorbed element palladium and sub-actinide elements, and eluting the element palladium out in a nitrate form, wherein the thiourea concentration of the nitric acid aqueous solution of thiourea is 0.2mol/L, and the nitric acid concentration is 0.1mol/L; and after the element palladium is eluted out in a nitrate form, using saltpeter solution with the pH (potential of hydrogen) being 6.5 to elute the chromatographic column with the adsorbed sub-actinide elements and eluting the sub-actinide elements out in a nitrate form. The method is simple, efficient, high in selectivity of the chromatographic column and effective in separation. |
