Performance Characteristics of Modified Paraffin Impregnated Graphite Electrodes—Testing of Different Carbon Nanotubes Binders

Abstract

The electrochemical properties of modified paraffin impregnated graphite electrodes (PIGEs) were tested throughout an electrochemical determination of Cu(II). The PIGEs were modified either by casting of carbon nanotubes suspension on prepared electrode surface or its abrasive deposition was used. Ten types of PIGE-modified electrodes, differed in type of dispersing agent used for CNT treatment and manner of modification, were evaluated. Chemometric characteristics of measurements were calculated and compared.
