Nanometalpolymers as ion-selective sensors

Abstract

The feasibility of usage of metal-polymer composites (PSE-1 polystyrene matrix) as electrode-active elements of solid-state potentiometric sensors for direct determination of heavy-metal ions in aqueous solutions has benn studied. The properties of electrode-active elements based on composites containing nickel, cobalt, and silver nano- and microparticles in a polystyrene matrix have been investigated, and the potentiometric selectivity coefficients have been determined for every composites.
