General description

Poly(ethyleneimine) (PEI) solution is an amine based chelating ligand that can be prepared by the polymerization of arizidine. It can be impregnated to form an anion exchange membrane for chromatography applications.

Application

PEI can be used as a complexing agent in the fabrication of composite membranes, which can be used in filtration of metals from the aqueous solution.
