Fe₃O₄-Polyaniline Nanocomposite for Non-enzymatic Electrochemical Detection of 2,4-Dichlorophenoxyacetic Acid.

ABSTRACT: This study proposes the development of an electrochemical sensor based on fabrication of a glassy carbon electrode (GCE) with Fe₃O₄-polyaniline (Fe₃O₄-PANI) nanocomposite, which was further used for enzyme-less detection of 2,4-dichlorophenoxyacetic acid (2,4-D) in aqueous medium. Spectroscopic studies, microstructural studies, and elemental analysis established the formation of Fe₃O₄ nanoparticles with polyaniline coating. The fabricated Fe₃O₄-PANI-GCE was characterized by electrochemical techniques like cyclic voltammetry and electrochemical impedance spectroscopy. The electrochemical response of 2,4-D on Fe₃O₄-PANI-GCE was evaluated by performing cyclic voltammetry and amperomet
