Synthesis, characterization and analytical applications of lead (II) selective polyacrylonitrile thorium (IV) phosphate: a novel fibrous ion exchanger

Some investigations on the preparative procedures of fibrous polyacrylonitrile thorium (IV) phosphate (PANThP) are reported. This new fibrous ion exchanger has been characterized on the basis of SEM and the ion exchange studies. The distribution studies reveal that the exchanger is highly selective for Pb(II). On this basis some useful binary separations of Pb(II) from other metal ions have been performed on its column indicating its useful environmental applications.
