An electrochemical investigation and reduction mechanism of 3, 5-Dinitrobenzoic acid at a glassy carbon electrode: A voltammetric study

► This work describes the determination of 3, 5- Dinitrobenzoic acid at GCE. ► Number of electrons, rate constant, diffusion and transfer coefficients, LOD and LOQ values were evaluated. ► The repeatability and reproducibility studies show that GCE was the good electrode for the determination of 3, 5-DNBA. ► The surfactant CTAB was found to exhibit a better response towards 3, 5-DNBA in compare SDS and TX-100. ► By using EIS studies the electron transfer rate at GCE was better in comparison with Pt electrode.
