Abstract RU 2062810 C1

FIELD: extraction of scandium. SUBSTANCE: method is carried out by sorption of scandium from hydrochloric solutions with the help of N-(2-oxypropyl)-N′-(2-oxy-3-pyridinium propyl)-N"-methylene phosphonium polyethylene polyamine followed by washing and by desorption. Said washing takes place with the help of water, desorption being carried out by carbonate or fluoride solutions. EFFECT: improves efficiency of the method. 2 tbl
