Abstract: Coated wire electrodes were prepared by coating PVC membrane on a platinum wirewhich had been modified with polyaniline or polyvinyl alcohol (containing a redox pair of K4Fe(CN)6/K3Fe(CN)6 and Lidocaine)respectively. The electrodes prepared not only havemerits of Pt wire coated. with PVC membrame, but also an improved stability.

Key words: Ion-salective electrode, Coatea wire electrode, Lidocaine
