Construction of Au nanoparticles on choline chloride modified glassy carbon electrode for sensitive detection of nitrite

A nanomaterial composed of cobalt nanoparticles, poly(3,4-ethylenedioxythiophene) and graphene with high electrocatalytic activity for nitrite oxidation

“…Since electrochemical oxidation of nitrite typically involves a large overpotential at the surfaces of the un-modified carbon electrodes, the detection of nitrite tends to suffer from interference by other more easily oxidized compounds. To overcome this problem, various modified electrodes have been constructed such as polymer film modified electrodes [9], nanoparticles modified electrodes [10,11], surfactant modified glassy carbon electrode [12], and carbon nanotube modified electrodes [8,13,14].…”

One-pot preparation of Au-RGO/PDDA nanocomposites and their application for nitrite sensing

“…So it is of significant importance to detect nitrites in food, water and environmental samples. Many analytical methods based on different principles, including fluorescence spectrophotometry [5], microchip capillary electrophoresis [6], chemiluminescence [7], electrochemical methods [8,9], and high performance liquid chromatography [10] have been developed. Compared with other detection techniques, the electrochemical methods are proved to be popular tools ascribed to their advantages of stability, selectivity, and simple and easy fabrication process.…”

Determination of nitrite in tap water: A comparative study between cerium, titanium and selenium dioxide doped reduced graphene oxide modified glassy carbon electrodes

“…These salts are present in the soil, sometimes in high quantity, which can cause their presence in high level in natural waters [3]. The potential metabolites of nitrite could be N-nitroso compounds, which possess carcinogenic effect [4][5][6]. Nitrites also can cause different health implications such as gastric and nasopharyngeal problems when people are seriously exposed [7][8][9].…”
