Abstract

Essential oil of bentazon- treated plants were extracted and herbicide content analyzed by electrochemical method. For this propose, carbon paste electrode was modified using ZnFe₂O₄ anchored on reduced graphene oxide which synthesized by solvothermal approach. The nature and morphology of nanoparticles were characterized using XRD, FT-IR and Fe- SEM image. Under optimal experimental condition, modified electrode produces powerful oxidation signal for bentazon at +0.95 V (vs. Ag/AgCl). The anodic current was increased linearly with bentazon concentration in the range of 0.1 -20.0 µmol L^-1 with a detection limit of 0.07 µmol L^-1. The practical usage of modified electrode was evaluated by electro analysis of extracted bentzon residues at three applied doses which revealed reasonable results.
