| description | The invention relates to a composition and method for producing a solid extracting agent for extraction of scandium from sulfuric acid solutions. There is provided a solid extracting agent (Solex) for extraction of scandium from scandium-containing solutions comprising a styrene-divinylbenzene matrix with di-(2-ethylhexyl) phosphoric acid. The extracting agent further comprises tri-n-octylphosphine oxide, tributyl phosphate, isododecane, in the following ratio of components, wt.%: di-(2-ethylhexyl) phosphoric acid 32.0 - 37.5, tri-n-octylphosphine oxide 4.2 - 8.0, tributyl phosphate 0.8 - 1.7, isododecane 16.7 - 20.0, the remainder styrene-divinylbenzene, with the styrene/divinylbenzene ratio in the matrix equal to 75-80 to 20-25 wt.%. There is also provided a method of producing the Solex. The technical result is the production of a scandium-selective Solex with a high dynamic exchange capacity.
L'invention concerne la composition et un procédé d'obtention d'un agent d'extraction pour extraire de scandium à partir de solutions d'acide sulfurique. L'invention porte sur un agent d'extraction (TVEKS) pour l'extraction de scandium à partir de solutions contenant du scandium contenant une matrice styrène-divinylbenzène avec un acide di-(2éthylhexyl) phosphorique. Il comprend en outre un tri-n-octylphosphinoxyde, un tributylphosphate, un isododécane, avec un rapport de composants suivants, en % en masse : di-(2-éthylhexyl)phosphorique 32,0-37,5, tri-n-octylphosphinoxyde 4,2 - 8,0, tributylphosphate 0,8 - 1,7, isododécane 16,7 - 20,0, styrène-divinylbenzène constituant le reste, le rapport entre styrène et divinylbenzène dans la matrice égal à 75-80 à 20-25 % % en masse. L'invention concerne également un procédé de fabrication de TVEKS. Le résultat technique consiste à obtenir un TVEKS sélectif au scandium avec une capacité d'échange à dynamisme élevé. |
