Abstract:A neutral
extractant, tetra(tert-butyl)-calix[4]bis[(4,4′-dimethyl-1,2-phenelyene)-crown-6]
(TTCalixB6), was prepared. The extraction equilibrium of Cs(I), Na(I),
K(I), and Rb(I) and some coexisting metals Sr(II), Ba(II), Fe(III),
and Ru(III) with TTCalixB6 was investigated in the range of 0.42–6.0
M HNO3. The effects of two types of organic diluents o-nitroanisole, an electron donor, and chloroform, an electron
acceptor, on the extraction of TTCalixB6 were examined. It showed
a high extraction abil… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
