Abstract

This study describes the preparation and analytical performance of polymer-modified electrodes with anti-fouling or occluding properties. Permselective coatings such as Nafion and hydrolyzed cellulose acetate (CA) were shown to impart higher selectivity, sensitivity, and stability to electrodes probably by excluding any unwanted matrix constituents from the electrode surface while allowing diffusional transport of the target analyte to the electrode surface. Applications described include the anodic stripping voltammetry of Pb(II) ions in the presence of surface-active non-electroactive compounds, and the analysis of phenol (to represent a surface-fouling electroactive analyte) using flow-injection amperometry.
