AKÜ FEMÜBİD 14 (2014) 011201 2 compound 8 is selective against Na metal, while the compound 9 is selective, especially against Hg 2+ cation. Additionally It has been observed from the dichromate anion extraction studies that the compound 6 transported large amounts of Na 2 Cr 2 O 7 from aqueous phase into the organic phase.
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.
