Electrochemical Detection and Degradation of Carbendazim at Poly (Vat Violet 2r) Modified GCE

Abstract

To increase the electrochemical activity of the working electrode, vat violet 2R dye was electro-polymerized on the GCE surface i.e., poly (VVR)/GCE. Utilizing various voltammetric techniques including such cyclic voltammetric (CV), differential pulse voltammetric (DPV), and square wave voltammetric (SWV) technique, the fabricated glassy carbon electrode demonstrated excellent electrocatalytic behaviour against the electro-oxidation of carbendazim (CBM) in a 0.2 M PBS 3.0 pH. There has been observed a well resolution peak of the CBM with enhancement in the current for the developed GCE. The impact of electroanalytical parameters such as accumulation time, temperature variation, pH, heterogeneous rate, transfer coefficient, sweep rate, activation energy, as well as total count of electrons and protons have been evaluated in the CBM electro-oxidation mechanism. The real samples like water and soil samples were investigated using voltammetric techniques. The developed sensor is sensitive for the investigation of fungicide CBM by the determination of detection and quantification limit of CBM.
