Abstract
A rapid extraction separation of trace amounts of yttrium from strontium with a nitrobenzene solution of sodium dicarbollylcobaltate (NaDCC) in the presence of polyethylene glycol having mean relative molecular weight 400 (PEG 400) and tetrasodium salt of ethylenediamine-N,N,N′,N′-tetraacetic acid (Na4L) in the aqueous phase was developed. The separation factor α(Sr/Y) was substantially higher than 106. This water-nitrobenzene extraction system can be applied for the efficient separation of carrier-free 90Y from a 90Y/90Sr generator.
