Abstract
The present invention provides an ion selective resin templated for Pb(II) ion, said resin synthesized by the steps of: copolymerizing styrene monomers with lead vinylbenzoate complexes; cross-linking said complexes with divinylbenzene; removing said Pb(II) ion by acid washing thereby creating cavities templated for Pb(II) ion. Also provided is an ion selective electrode which utilizes a Pb(II) ion templated ion exchange resin.
