摘要

The separation of yttrium from lanthanide elements by extraction chromatography, using di(2-ethylhexyl) orthophosphoric acid (HDEHP) as the stationary phase, kieselguhr as the inert support and HNO sub 3 solution as the mobile phase, was studied. More than 50% of yttrium, initially present, was obtained in the state, by eluting this element with a HNO sub 3 solution with concentration ranging from 4.5 N to 5.0 N. The substoichiometric technique was applied to the determination of yttrium. This element was partially complexed with EDTA and the Y exp 3+ ions remaining in the solution were separated from the (Y-EDTA) chelate by means of a cationic resin. The sensitivity, precision and accuracy that may be expected in the analytical results were also studied. (Atomindex citation 11:564336)
