| titleOfInvention | Method for separating heating element Cs and Sr from high radioactive waste |
| abstract | The invention discloses a method of separating heating elements Cs and Sr from high level radioactive waste. The method contains the following steps: (1) concentrated nitric acid is added into the nitrate solution of high level radioactive waste that the secondary actinide is separated; the concentration of the nitric acid is adjusted to 3.5-4.4 mol/L; (2) the nitrate solution of high level radioactive waste that the nitric acid concentration is adjusted passes by a chromatographic column filled with adsorbent A, and the heating element Cs is absorbed by the chromatographic column filled with adsorbent A; (3) after the nitrate solution of high level radioactive waste that the nitric acid concentration is adjusted flowing out of the chromatographic column filled with adsorbent A, water is added and the concentration of the nitric acid is adjusted to 1.5-2.5 mol/L; and when the solution passes by the a chromatographic column filled with adsorbent B, the heating element Sr is absorbed by the chromatographic column filled with adsorbent B. The method is simple with high efficiency. The concentration of the nitric acid is similar when the two chromatographic column adsorptions are separated, which is convenient to be adjusted. |
