Совместная сорбция скандия и тория фосфорсодержащими ионообенными смолами

Abstract

The possibility of scandium recovery from sulfuric acid solutions by phosphorus containing ion-exchangers in presence of thorium was explored. The ampholyte Tulsion CH 93 had a largest value of scandium capacity. Increasing of thorium content in solution resulted in decrease of scandium recovery. Dynamic sorption parameters were identical for both elements. Scandium recovery in presence of thorium by phosphorus containing ionexchangers is possible, but this requires additional separation of elements.
