摘要：
The extraction of 90Sr and 90Y from alkaline carbonate media with tetrachloroethylene solutions of p-tert-butyl and p-isononylcalix[8]arenes with various substituents in the lower rim was studied. The dependences of the 90Sr and 90Y distribution ratios on pH of the aqueous phase in the interval from 11 to 14 were studied. Among the calixarenes tested, p-alkylcalix[8]arenes with a bridging group in the lower rim show the highest performance in the extraction of 90Sr and 90Y. © 2018, Pleiades Publishing, Inc.
