摘要：
The present work confirms the high separation ability of purified Cyanex 301 towards trivalent americium over europium in liquid-liquid extraction. Solvent 2-nitrophenyl octyl ether (NPOE) lowered the partitioning of Am3+ but remained the separation ability over europium. Solvent toluene and 3-octanone lowered the separation factor to -1000. It is feasible to separate Am3+ from Eu3+ by Cyanex 301 which was immobilized in the macro porous polymer (MPP). 3-Octanone is a suitable solvent for dissolving NH4OH-saponified Cyanex 301 and MPP is a suitable solid supported material for column operation. A five-step column experiment demonstrated the feasibility to separate Am3+ from Eu3+ in column which was packed with Cyanex 301-impregnated MPP.
