Abstract
A method for the separation of actinides from lanthanides present in a trivalent state in an acidic aqueous solution. Said method consists in selectively extracting in an organic solvent the actinides present in said solution, by bringing said aqueous solution into contact with an organic solvent comprising a system of extractants constituted by an acidic organo-phosphorated compound containing at least one electron doner sulfur atom such as di-2-ethylhexyl-dithio-phosphoric acid, and by a neutral organophosphorated compound containing at least one electron-doner oxygen atom such as tributyl phosphate.
