An electrochemical sensor for flubendiamide insecticide analysis based on chitosan/reduced graphene oxide

Abstract

In the present work, a reduced graphene oxide/chitosan pencil electrode (rGO/CHI/PGE) was successfully synthesized for the analysis of flubendiamide (FBD). The graphene oxide (GO) was reduced by a quick, efficient, and green electrochemical method without the use of any reducing chemicals. Structural and morphological analyses of the rGO/CHI/PGE were carried out. Under optimized parameters, the detection limit was found to be 9 nM. This developed electrochemical device was successfully used as a simple and cost-effective electrode for FBD detection in white rice samples.
