Abstract :
Nanostructured Fe2O3-ZnO modified GCE electrochemical nanosensor has been developed for the determination of dinobuton pesticide in environmental samples. The electrochemical behavior of the dinobuton pesticide was examined by cyclic and differential pulse voltammetry. The conventional electrode signal was an estimable response on the Fe2O3-ZnO/GCE, due to noble electrical conductivity and the tolerable electrostatic interface between Fe2O3 and ZnO. Under the optimum conditions, a linear association was obtained from 0.05 to 30.00 µg•mL-1 between the peak current and the concentration of dinobuton, significant detection limit of 0.01200 µg•mL-1 and to a quantification limit of 0.03636 µg•mL-1. The established procedure was magnificently applied to the determination of dinobuton pesticide in environmental (water and soil) samples.
