摘要：

In this communication, a method for encapsulation of a polymeric resin using radiation technology is reported. The quaternary ammonium resin, polydiallyidimethylammonium chloride (PDADMAC) was incorporated in the core of a preformed hollow polyethersulfone microcapsule, using radiation technology, for the extraction of anions from aqueous Solutions. The idea was to introduce the monomer into the porous microcapsules and initiate polymerization by radiation to trap the polymer formed inside the Capsule. The resultant capsule was able to take up and exchange some anions (F-, Cl-, Br-, NO32- and SO42-) at relatively low concentrations. (C) 2008 Elsevier Ltd. All rights reserved.
