Sažetak
Electrochemical characterization of ascorbic acid oxidation on a graphite screen printed electrode (SPE) modified with La3+/Co3O4nanocubes is performed by applying cyclic voltammetry (CV), chronoamperometry (CHA), and differential pulse voltammetry (DPV) techniques. Synthesized La3+/Co3O4nanocubes for SPE modification, La3+/Co3O4/SPE, enhance the ascorbic acid electrooxidation kinetics by reducing the anodic overpotential. Excellent La3+/Co3O4/SPE electrochemical properties provide sensitive ascorbic acid voltammetric determination with low detection limit, good stability and quick response towards electrooxidation of ascorbic acid as compared to bare SPE. Under optimized conditions, DPV current demonstrates a linear response for ascorbic acid over a concentration range of 1.0 to 900.0 mM with a correlation coefficient of 0.9997, and detection limit (LOD) (S/N = 3) = 0.3 mM. The proposed procedure offers a potential application for producing the sensor with good repeatability. Also, fast response of fabricated sensor can allow a real-time analysis of real samples.
