| titleOfInvention | A kind of method from high-level waste separating heating element Cs and Sr |
| abstract | The invention discloses a kind of method, comprise the steps: that (1) adds red fuming nitric acid (RFNA) concentration of nitric acid is adjusted into 3.5～4.4 mol in the nitrate solution of the high-level waste of isolating time actinides from high-level waste separating heating element Cs and Sr; (2) nitrate solution that will adjust the high-level waste behind the concentration of nitric acid is by being filled with the chromatographic column of adsorbent A, and heating element Cs is filled with the chromatographic column absorption of adsorbent A; (3) nitrate solution of adjusting the high-level waste behind the concentration of nitric acid flows out and adds water after the chromatographic column that is filled with adsorbent A to adjust the concentration of nitric acid be 1.5～2.5 mol, by being filled with the chromatographic column of adsorbent B, heating element Sr is filled with the chromatographic column absorption of adsorbent B.The inventive method is succinctly efficient, and the concentration of nitric acid is approaching during twice chromatographic column adsorbing separation, is convenient to adjust. |
