Synthesis of 2-phenoxyethanol/formaldehyde copolymer beads by dispersion polycondensation and their adsorption properties for copper ions after polyamine modification
Abstract:A B S T R A C TTwo kinds of novel chelating resins were prepared by surface modification of 2-phenoxyethanol/formaldehyde copolymer beads (PB) with ethylenediamine (EA) and diethylenetriamine (DEA) (denoted as PB-EA and PB-DEA, respectively). The obtained resins were characterized by infrared spectra, scanning electron microscopy (SEM), and elemental analysis to demonstrate successful surface modification. The adsorption properties of the resins for metal ions are investigated. The results showed that the resi… 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.
