Electrochemical sensing of nitrite in drinking water using multi-walled carbon nanotubes modified platinum electrode

Year: 2024

Type: article

Abstract: Aim: The scope of the present study was to elaborate a nitrite electrochemical sensor using multi-walled carbon nanotubes (MWCNTs) modified Pt electrode. Methods: The electrocatalytic activity of the proposed sensor was studied by cyclic voltammetry (CV), chronoamperometry (ChAm), and electrochemical impedance spectroscopy (EIS). Then electrochemical detection of nitrite was performed using square wave voltammetry (SWV). Results: The MWCNTs/Pt electrode exhibits good electrocatalytic activity for the oxidation of nitrite in neutral pH. Subsequently, the fabricated electrochemical sensor shows a high sensitivity for the NO2– determination and a low limit of detection (LOD) (0.1 µM) in a wide linear concentration range (1.0–1,000 µM). Conclusions: This electrochemical sensor has cost-effective, anti-interference capability as well as good stability, reproducibility, and applicability.
