Solid–liquid extraction of iodide and bromide from aqueous media by a new water-insoluble phenoxycalix[4]pyrrole-epichlorohydrin polymer

Abstract

A phenoxycalix[4]pyrrole-epichlorohydrin based extractant was easily synthesized for the first time and used for iodide and bromide extraction from aqueous media.
