Beschreibung
Zusammenfassung:	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.
