Abstract

A simple, rapid and sensitive electrochemical method was developed for the determination of the organophosphate insecticide Fenamiphos (FNP) and its main metabolite fenamiphos-sulphoxide (FNX). The electrochemical behaviour was investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) on a bare glassy carbon (GC) electrode. An oxidation peak was obtained for FNP and FNX at a bare GC electrode. The anodic peak showed irreversible behaviour and a mechanism of reaction at the electrode surface based on a mixed adsorption and diffusion controlled reaction is suggested. The obtained percentage of recovery showed good agreement compared to those reference values when GC-MS was used as a reference method.
