Title : Development of modified electrodes for electrochemical analysis of flubendiamide under UV excitation.
Abstract:
In this study, a new pencil graphite electrode (PGE) modified with TiO2/Bi nanoparticles was successfully developed for quantitative measurements of flubendiamide (FBD) using differential pulse voltammetry (DPV). The detection limit (LOD) and quantification limit (LOQ) were found to be 1.95 × 10 −7 mol. L −1 and 6.48 × 10 −7 mol. L −1, respectively. A linear relationship was observed between the differential response of the modified electrode's pulse voltammetry and the concentration of FBD in the detection range of 8.10-7 mol. L-1 to 10-5 mol. L-1. The influence of interfering species was evaluated, and the results showed that the developed sensor exhibited high selectivity for FBD. Additionally, the proposed electrode showed high sensitivity for the determination of FBD in wastewater samples
