Laboratory study was performed to examine the extraction of rare-earth elements and americium with a synergic mixture of chlorinated cobalt dicarbollide (ChDC) and di-2-ethylhexyl phosphoric acid (D2EHPA). It was shown that this extractive agent effectively extracts TPEs and REEs from a nitrate solution of highly radioactive wastes and can extract americium into a separate fraction with good purification to removes. The scheme suggested for extractive isolation of TPEs has a number of advantages over the schemes previously taken for verification.

ChCD和D2EHPA混合物在辐照燃料元件中生成的弱酸残液中的REE和TPU的萃取级分的可能性

进行了实验室研究，以研究氯化二碳酸钴（ChDC）和二-2-乙基己基磷酸（D2EHPA）的增效混合物对稀土元素和extraction的提取。结果表明，该萃取剂可有效地从高放射性废物的硝酸盐溶液中萃取TPE和REE，并可将with提取成单独的馏分，并具有良好的净化效果。与以前用于验证的方案相比，建议用于TPE提取分离的方案具有许多优点。
