Abstract

In this paper cyclic voltammetry (CV) and linear-sweep voltammetry (LSV) experiments were conducted in order to compare the electroactivity of three types of carbon nanofibers based composite electrodes, i.e., natural and synthetic zeolite modified electrodes and a simple carbon nanofibers electrode for pentachlorophenol (PCP) detection. The enhancement factor of electrode sensitivity for the determination of PCP at the tested electrodes was determined by applying a chemical preconcentration step prior to voltammetric quantification. Synthetic-zeolite modified electrode exhibited a larger electroactivity than the other two electrodes, due to a better ability of synthetic zeolite particles from the electrode surface to retain PCP molecules, without inactivation of electroactive sites.
