Abstract

A nanocomposite with highly dispersed AuNPs coated poly[2-(methacryloyloxy) ethyl] trimethylammonium chloride (PMTC) supported upon jute carbon (AuNPs-PMTC-JC) was prepared in aqueous medium for the selective determination of nitrite (NO2) ions. Quaternary ammonium groups of PMTC in the nanocomposite results in a positive zeta potential, elevating the electrocatalytic properties of the modified electrode for negatively charged NO2 ions oxidation. The AuNPs-PMTC-JC composite was characterized using UV–vis, FESEM, TEM, SAED, XRD, EDS, CV and EIS. The LOD (S/N = 3) value for NO2 determination is 0.16 µM in the linear range of 0.4–706.5 µM based on the i-t current response, while it is 1.28 µM based on CV responses in the wide range of 10–1000 µM. The modified electrode is highly selective for NO2 ions and shows highly stable, and reproducible results. CV was used to analyze tap water spiked with NO2 and a recovery close to 100 % was observed.
