The electrochemical properties of fenhexamid on bare glassy carbon electrode

Abstract

Study on electrochemical behaviour of fenhexamid (commercially available fungicide) was performed using repetitive cyclic voltammetry at glassy carbon electrode in different 0.1 Britton-Robinson buffers containg always 1% (v/v) methanol at potential step 5 mV and scan rate 50 mV s-1. It was found that fenhexamid is reversibly oxidized to 1-methylcyclohexanecarboxylic acid (2,3-dichloro-4-oxo-cyclohexa-2,5-dinylidine)-amide with the participation of two electrons and protons. It can be assumed that anodic oxidation of fenhexamid could be utilized to develop a simple and rapid voltammetric method for monitoring fenhexamid residues in the food safety control.
