    摘要: A process for the separation of the actinides and lanthanides present in the trivalent state in an acid aqueous solution, wherein the actinides present in such aqueous solution are extracted selectively in an organic solvent by bringing the solution into contact with an organic solvent comprising a first extracting agent formed by an organic bonding agent having an electron-donor nitrogen atom and a second extracting agent formed by an acid organosoluble organic compound able to exchange its H.sup.+ ions for metal ions or by metallic salt of such compound.Application to the nuclear industry, inter alia in the field of the treatment of aqueous effluents containing lanthanides and actinides, such an transuranic elements.
