Abstract

Sposób oddzielania ameryku(III) i ewentualnie kiuru od lantanowcowych produktów rozszczepienia w układach ekstrakcyjnych ciecz-ciecz, zwłaszcza w układach ekstrakcyjnych, gdzie fazę organiczną stanowią roztwory lipofilowych pochodnych BTBP w mieszaninach oktanolu z naftą lub roztwory TODGA w mieszaninach oktanolu z naftą, według wynalazku, polega na tym, że fazę organiczną poddaje się modyfikacji fizykochemicznej poprzez dodanie do rozcieńczalnika organicznego odpowiedniego modyfikatora lub zastąpienie rozcieńczalnika organicznego przez odpowiedni modyfikator, wybrany z grupy obejmującej ketony, etery, aromatyczne kwasy organiczne i ich pochodne, oraz aminy, niemieszającego się z wodą i zawierającego w swej cząsteczce jeden pierścień aromatyczny, w tym także heterocykliczny, lub mieszaniny wybranych z tej grupy modyfikatorów, w ilości od 2 do 100% masowych (bez uwzględniania stężenia ekstrahenta) do rozcieńczalnika organicznego, jakim są ciekłe węglowodory lub mieszanina węglowodorów, zwłaszcza nafta, albo ciekły alkohol alifatyczny, zwłaszcza 1-oktanol, lub mieszanina tych substancji.The method of separating America (III) and, optionally, chicken from lanthanide fission products in liquid-liquid extraction systems, especially in extraction systems, where the organic phase consists of solutions of lipophilic BTBP derivatives in mixtures of octanol with kerosene or TODGA solutions in mixtures of octanol with kerosene, according to the invention, consists in the fact that the organic phase is subjected to physicochemical modification by adding a suitable modifier to the organic diluent or replacing the organic diluent with a suitable modifier, selected from the group consisting of ketones, ethers, aromatic organic acids and their derivatives, and amines, immiscible with water and containing one aromatic ring in its molecule, including heterocyclic, or mixtures of modifiers selected from this group, in an amount of 2 to 100% by mass (without taking into account the concentration of the extractant) to the organic diluent, which is liquid carbon hydrogen or a mixture of hydrocarbons, especially kerosene, or liquid aliphatic alcohol, especially 1-octanol, or a mixture of these substances.
