Description 572-579
A novel voltammetric sensor, Ag@BaTiO3/rCF/GCE has been designed based on silver nanoparticle (AgNPs), barium
titanate (BaTiO3) and bio-inspired carbon derived from onion peel (OP) for the electrochemical determination of an organic
pollutant, resorcinol (RS). The nanocomposite has been synthesized by ultrasonic irradiation of BaTiO3 decorated on
reduced carbon flakes (rCF) on which the Ag nanoparticles (AgNPs) are stabilized. It has been characterized by
spectroscopic and microscopic techniques and Impedence spectroscopy. Its electrochemical activity is studied by the surface
modification of the glassy carbon electrode (GCE) through cyclic voltammetry (CV) and differential pulse voltammetry
(DPV). The results show a considerable decrease in the Rct equal to 239Ω which confirms the surface modification of the
electrode. The slope value 0.7814 confirms that the electrocatalytic oxidation of RS is a typical adsorption-controlled
process. The linear concentration range of resorcinol detection varies from 6.66 to 131.67 μM with a LOD of 0.378 μM.
