Abstract

For the primary concentration of scandium from solutions of a multicomponent solution, phosphorus-containing resins are used as a mother liquor for sorption of uranium. For this purpose, phosphorus-containing ion exchangers such as Lewatit TP272, Purolite AA-03, POLION BMCC, Lewatit TP 260 and AXIONIT ECO-10A were used. According to the results of the static mood, a high degree of scandium extraction from the mother liquor of uranium sorption was achieved during sorption and desorption in the static mood by Lewatit 272 (80.1%) and Purolite AA-03 (75.6%) ion exchangers.
