A PVC membrane electrode for lead ions based on 4Ј-vinylbenzo-15-crown-5 homopolymer as membrane carrier was prepared. The electrode exhibits a Nernstian response for Pb 2ϩ ions over a wide concentration range (4.0 ϫ 10 Ϫ3 to 1.0 ϫ 10 Ϫ6 M), with a limit of detection of 7.0 ϫ 10 Ϫ7 M. It has a respo
