| Popis: | Pyrometallurgical processes for the purification of plutonium for defense create waste solutions containing actinides, mainly americium, in chloride medium. Studies have been undertaken to study the extraction of actinides in a chloride medium (hydrochloric acid mixed with concentrated salts such as LiCl, CaCl2, MgCl2, KCl) using pentaalkylpropanediamides as extractants. Plutonium(IV) is very easily extracted, but Am(III) needs a salting-out agent such as LiCl. Back extraction of trivalent cations is easy in HCl |
