Electrochemical Evaluation of Phanerocheaete Chrysosporium Based Carbon Paste Electrode with Potassium Ferricyanide Redox System

Year: 2015

Type: article

Abstract: In the present study, a modified carbon paste electrode is reported with fungal biomass of Phanerocheaete chrysosporium as the modifying agent. Cyclic voltammetric studies with the redox couple of [Fe(CN)6]3-/[Fe(CN)6]4- are used for electrochemical characterization of modified electrode. These studies revealed that the modified electrode has a greater electrochemical surface area, coverage capacity, and heterogeneous rate constant in comparison to unmodified electrode. Infrared spectra, atomic force and scanning electron microscopic images are used to characterize surface morphology of modified and unmodified electrode. In addition, Nyquist plots showed that charge transfer experienced less resistance on the modified electrode illustrating that Phanerocheaete chrysosporium has improved the electro catalytic efficiency of the carbon paste.
