Abstract
In this study, we report an effective electrochemical sensor of single-walled carbon nanotubes (SWCNTs)/Nafion glassy carbon electrode (SWCNTs/Nafion/GCE) for determination of dicapthon in water and agricultural food samples. The electroanalytical performance of SWCNTs/Nafion/GCE toward the reduction of dicapthon was analyzed via cyclic and differential pulse voltammetry. The optimum parameters like the effect of pH, concentration of dicapthon solution, scan rate, accumulation potential and accumulation time were thoroughly optimized. At electrochemical optimum conditions, voltammetric reduction peak exhibited a linear with the concentration of dicapthon from 0.2‒60.0 µg mL−1, with a detection limit of 0.036 µg mL−1. The modified electrochemical sensor showed good stability and reproducibility. The determination of dicapthon was examined with SWCNTs/Nafion/GCE in water and agricultural food samples.
