Separation of rare-earth and transplutonium elements by displacement chromatography on S-957 phosphonic ion exchanger

Sorption of transplutonium (TPE) and rare-earth (REE) elements on Purolite®S-957 ion exchanger containing phosphonic acid and sulfo groups was studied. Rare-earth elements are efficiently sorbed from weakly acidic solutions (≤0.1 M HNO 3 ). An increase in the solution acidity and introduction of sod...

Description
Summary:Sorption of transplutonium (TPE) and rare-earth (REE) elements on Purolite®S-957 ion exchanger containing phosphonic acid and sulfo groups was studied. Rare-earth elements are efficiently sorbed from weakly acidic solutions (≤0.1 M HNO 3 ). An increase in the solution acidity and introduction of sodium ions into the sorption medium lead to a decrease in the sorption. With S-957 resin, REE and TPE were separated for the first time on a phosphorus-containing sorbent by displacement chromatography in the presence of DTPA (diethylenetriaminepentaacetic acid).
