摘要
本工作以75Se、95Zr、109Pd为指示剂,试验并建立了以1 mol/L HNO3为上柱液介质和洗涤液,在DMG色层柱、硅胶柱、Bis-Ⅱ色层柱上分别选择性吸附Pd、Zr、Se,然后分别解吸的系统分离流程。该流程对Se的回收率接近90%,对Zr、Pd的回收率均大于90%,对90Sr、137Cs、152Eu等核素的去污因子均高于103。
A procedure including DMG resin column,silica gel column and Bis-Ⅱresin column was established to sequentially separate 79Se,93Zr and 107Pd from high level liquid waste（HLLW）.A simulated solution was prepared to test the procedure and 75Se,95Zr and 109Pd were used as tracers.The recovery of Se is near to 90%,and that of Pd and Zr are more than 90%,and the decontamination factors of 90Sr,137Cs and 152Eu are better than 103.
