Calixarene-functionalized graphene oxide composites for adsorption of neodymium ions from the aqueous phase

Abstract

Calixarene-functionalized graphene oxide (GO) composites were synthesized <italic>via</italic> esterification and polymerization of calix[<italic>n</italic>]arenes (<italic>n</italic> = 4, 6, 8) onto graphene oxide surfaces for the first time.
