“…Due to the high specificity of nitrate reductase (NaR) and the easy-to-handle operation of electrochemical device, various enzyme-based electrochemical detections for nitrate have been widely performed using combinations of NaR and different mediators to detect the This is the Pre-Published Version electron-transfers [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. However, the low redox potential of this enzyme and its matching mediators suffer from oxygen interferences.…”

“…Several reported spectrophotometric methods involve the use of common reactions, such as a reduction reaction followed by diazotization, 4,5 nitration reactions, 6,7 or others. 8,9 Other methods involve the use of ion chromatography 10 and specific ion electrodes. 11 The well-known spectrophotometric methods for the determination of nitrate are based on the nitration of phenolic compounds, 12,13 chromotrophic acids, 14 2,4-xylenol, 15,16 2,6-xylenol, 17 3,4-xylenol, 18,19 phenoldisulfonic acid, 20 brucine 21,22 and phenol.…”

“…23 De acordo com o limite recomendado pelas agências normativas, acima do limite aceitável, pode causar sérios danos à saúde humana e ao meio ambiente. 24,25 A modificação de eletrodos com NPs tem sido feita usando diferentes técnicas, tais como, decomposição térmica, 26 microemulsão, 27 e eletrodeposição. 28,29 Dentre elas, a eletrodeposição tem sido uma das mais empregadas, pois se trata de uma técnica simples, de baixo custo, de processamento à temperatura ambiente, além de possibilitar um maior controle no processo de nucleação e crescimento sobre a superfície do eletrodo, o qual é fundamental para a obtenção de NPs…”
