- Abstract
A novel and sensitive method has been described for voltammetric study and determination of trifluralin, commonly used herbicide, based on its electrochemical oxidation on modified glassy carbon electrode (GCE) with multi-walled carbon nanotubes (MWCNT) and nanomagnetic core-shell coated with fluconazole (FeO/SiO ~ FLU). CV studies indicated that the amine group of trifluralin oxidation process has a quasi-reversible and adsorption-like behavior in a mechanism with equal number of electrons and protons. The proposed sensor was found to quantify trifluralin by SWV in the range of 1.0 × 10-2.0 × 10 mol L, R = 0.998, detection limit (1.0 × 10 mol L) and repeatability (RSD = 1.99%, n = 10, for 1.0 × 10 mol L trifluralin). The interpretations of the theoretical calculations and experimental results have shown good adaptation to discuss the outer sphere electron transfer (ET) process on the fluconazole-immobilized FeO/SiO core-shell linked to carbon nanotube modified glassy carbon electrode. To further validate its possible application, the method was used for the quantification of trifluralin in water samples.
