Abstract
Abstract In this work, we reported electrochemical polymerization of methyl red for detection of 2-nitrophenol (2-NP), a known environmental pollutant and carcinogen. The electrochemically synthesized polymethyl red (PMR) was characterized using FESEM, FTIR, XPS, XEDS and cyclic voltammetry. Due to its electro-catalytic property, the synthesized PMR displayed high sensitivity towards electro-reduction of 2-NP at room conditions. The limit of detection and sensitivity were found to be 0.15 μM (S/N = 3) and 95.0 μAμM-1 cm−2 respectively. It also produced highly reproducible, repeatable and stable responses to 2-NP and also good applicability in real environmental samples analysis. Based on the result of these electrochemical studies, PMR modified GCE is a promising electrochemical sensor probe for 2-NP for human health protection and environmental management.
