Abstrakt:	Deep purification of the stripped 90Y obtained after the 90Sr/90Y pair extraction separation with D2EHPA from chemical impurities (Cr, Mn, Ni, Pb, Fe, Zr) employing the TODGA-containing sorbent AXIONIT MND 40T was considered. Also, a two-stage sorption separation of the 90Sr/90Y pair without using the extraction method was developed. At the first stage the 90Y was separated from 90Sr with Purolite D5041 phosphate cation exchange resin, and at the second stage, 90Y deep purification was carried out on the AXIONIT MND 40T sorbent. The prepared 90Y in radiochemical purity meets the requirements for radiopharmaceuticals. [ABSTRACT FROM AUTHOR]
