摘要：
In the present study, a novel pencil graphite electrode (PGE) modified with clay microparticles was successfully developed for the quantitative measurements of flubendiamide (FBD) using differential pulse voltammetry (DPV). The transfer coefficient (alpha) and the diffusion coefficient (D) were calculated as 0.6 and 4.560 x 10(-4) cm(2) s(-1) , respectively. A linear relationship was observed between differential pulse voltammetry response of the modified electrode and the concentration of FBD in the range of 0.8-300 mu M. The influence of interfering species was evaluated and the obtained results showed that the developed sensor has a high selectivity for FBD. Moreover, the proposed electrode exhibited high sensitivity for the FBD determination in wastewater, river water and rice samples.
