“…Miranda et al [ 73 ] used vanadium (III) to reduce nitrate and detect nitrate and nitrite concentrations simultaneously, employing the acidic Griess reaction. Catalan-Carrio et al [ 74 ] developed a compact and portable device that could detect nitrite and nitrate in water samples using the multivariate analysis of color readings from the device’s sensing sites. The device incorporated both sample analysis and calibration sites.…”

The health and integrity of our water sources are vital for the existence of all forms of life. However, with the growth in population and anthropogenic activities, the quality of water is being impacted globally, particularly due to a widespread problem of nitrate contamination that poses numerous health risks. To address this issue, investigations into various detection methods for the development of in situ real-time monitoring devices have attracted the attention of many researchers. Among the most prominent detection methods are chromatography, colorimetry, electrochemistry, and spectroscopy. While all these methods have their pros and cons, electrochemical and optical methods have emerged as robust and efficient techniques that offer cost-effective, accurate, sensitive, and reliable measurements. This review provides an overview of techniques that are ideal for field-deployable nitrate sensing applications, with an emphasis on electrochemical and optical detection methods. It discusses the underlying principles, recent advances, and various measurement techniques. Additionally, the review explores the current developments in real-time nitrate sensors and discusses the challenges of real-time implementation.

In order to monitor the concentration of nitrate in groundwater and evaluate water quality, a specialized sensor has been developed to solve the problems of the passivation effect, short life and poor repeatability of electrodes in conventional electrochemical detection, a novel preparation method of copper-sensitive film was proposed, and the method was combined with a microelectrochemical sensing electrode to detect nitrate in water. Microfabrication technology was used to prepare the micro sensor electrode. A total of 0.05 mol/L CuSO4 was added into the supporting electrolyte, and the dissolution and deposition of copper on the surface of the working electrode and the catalytic reduction reaction of nitrate ions were performed. On-line cleaning of microelectrode, in situ deposition of copper-sensitive film and detection of nitrate concentration in water were realized, respectively. An on-line modified electrode was used to detect the nitrate standard sample, achieving a high detection sensitivity (0.031 μA/[μmol L−1]) in the concentration range of 0–3500 μmol/L. The relative standard deviation of the same nitrate standard sample repeated for 15 times was only 2.48%, which improved the long-term repeatability of nitrate detection, and, at the same time, an on-line system was adopted that included an on-line detection system (DS) and a wireless transmission system (WS).
