Abstract

A simple, rapid, and sensitive electrochemical method was developed for the determination of the organophosphate insecticide fenamiphos (FNP) and its main metabolite fenamiphos sulfoxide (FNX). The electrochemical behaviour was investigated by cyclic voltammetry and differential pulse voltammetry on a bare glassy carbon electrode. An oxidation peak was obtained for FNP and FNX at a bare glassy carbon 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.
