Abstract
From past decades, carbon-based electrochemical sensing electrode materials were developed. Among the all, carbon black (CB) based electrode materials achieved a predominant position in electrochemical sensing application due to its low cost, unique physical and electrochemical properties. Herein, we have fabricated pristine CB as an active electrode material for the detection of VAN (VAN). Initially, the surface and nature of pristine CB material were studied by various characterization methods such as XRD, and HR-TEM analysis. As characterized pristine CB was used for the fabrication of carbon based electrode for electrochemical sensing of VAN. For that, the reported CB/SPCE was subjected to various electrochemical techniques such as cyclic voltammetry and differential pulse voltammetry methods. From the analysis, a low level detection limit (0.039 μand high sensitivity of (0.096 μAμM-1cm-2) was achieved for CB/SPCE towards sensing of VAN. Furthermore, the fabricated CB/SPCE electrode shows excellent reproducibility and stability as compared to other carbon based electrode materials. Therefore, we believed that the CB/SPCE sensor is enough electrode for the electrochemical sensing of VAN.
