| Abstract: | A rapid extraction separation of trace amounts of yttrium from strontium with a nitrobenzene solution of sodium dicarbollylcobaltate (NaDCC) and 18-crown-6 in the presence of tetrasodium salt of ethylenediamine-N,N,N",N"- tetraacetic acid (Na4L) in the aqueous phase was developed. The separation factor a(Sr/Y) was substantially higher than 106. This water-nitrobenzene extraction system can be applied for efficient separation of carrier-free 90Y from 90Sr/90Y generator. |
