ABSTRACT

In this communication, a method for encapsulation of a polymeric resin using radiation technology is  reported.  The quaternary ammonium resin, polydiallyl  dimethyl ammonium chloride (PDADMAC) was incorporated in the core of a preformed hollow polyether sulfone micro capsule, using radiation technology, for the extraction of an ions 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. There sultant capsule was able to take up and exchange some anions (F-, Cl-, Br-,NO32- and SO4 2-)at relatively low  concentrations.
