Resumen:
In this work we present a new crosslinked hydrophilic resin (weakly basic anion exchange resin): A obtained from polyethylenimine (PEI), (a linear hydrophili polymer) and a diepoxide compound (hydrophilic monomer) in aqueous medium. Once obtained, the free amine groups (primary, secondary and tertiary) contained in the resin, were modified through a substitution reaction to yield a strongly basic anion exchange resin: B. Both products experimental condition were assayed (variation of pH and concentration), using a batch system at room temperature and a determinated time of contact, noticing high capacity of retention.
