Nitrite and nitrate are widely found in various water environments but the potential toxicity of nitrite and nitrate poses a great threat to human health. Recently, many methods have been developed to detect nitrate and nitrite in water. One of them is to use graphene-based materials. Graphene is a two-dimensional carbon nano-material with sp 2 hybrid orbital, which has a large surface area and excellent conductivity and electron transfer ability. It is widely used for modifying electrodes for electrochemical sensors. Graphene based electrochemical sensors have the advantages of being low cost, effective and efficient for nitrite and nitrate detection. This paper reviews the application of graphene-based nanomaterials for electrochemical detection of nitrate and nitrite in water. The properties and advantages of the electrodes were modified by graphene, graphene oxide and reduced graphene oxide nanocomposite in the development of nitrite sensors are discussed in detail. Based on the review, the paper summarizes the working conditions and performance of different sensors, including working potential, pH, detection range, detection limit, sensitivity, reproducibility, repeatability and long-term stability. Furthermore, the challenges and suggestions for future research on the application of graphene-based nanocomposite electrochemical sensors for nitrite detection are also highlighted.Sensors 2020, 20, 54 2 of 35 deaths. Nitrite in drinking water can irreversibly convert hemoglobin into methemoglobin, which results in a decrease in oxygen carrying capacity in the blood [5]. It can react with secondary amines to produce n-nitrosamines, which are likely to lead to gastric cancer [6]. Since nitrate is converted into nitrite in the digestive tract, it also very harmful to the human body [7]. It can also lead to the unnatural reproduction of aquatic plants and algae, leading to "red tides" and the death of fish [8,9]. The United States (U.S.) Environmental Protection Agency has limited the nitrite and nitrate content in drinking water to 1 mg/L and 10 mg/L [10] and other countries have made similar regulations. The concentration of nitrate and nitrite in water has become one of the indexes for evaluating water quality. Therefore, the detection of nitrate and nitrite in water samples at low concentrations has been the focus of research [11].So far, many methods have been used to detect nitrate and nitrite, such as spectrophotometry [12][13][14], chemiluminescence [15,16], chromatography [17], fluorescence [18,19] and electrochemical methods [20][21][22]. Among them, the electrochemical method is one of the most commonly used detection methods because of its advantages of being low cost, fast, direct and high efficiency [23]. However, the sensitivity and accuracy of the electrodes are reduced because of disturbance by other substances. Bare electrodes need higher applied potential, which limits the application of bare electrodes [24]. Therefore, electrochemical techniques based on modified electrodes have been extensively...

“…However, the introduction of most inorganic nanomaterials cannot remarkably improve the performance of the electrochemical nitrite sensor because these nanomaterials possess limited electrocatalytic activity. Very recently, transition metal hydroxides have been demonstrated to have high electrocatalytic activity , and thus are promising for construction of electrochemical nitrite sensor with good performance. Moreover, to the best of our knowledge, almost no literature reported the use of nanocomposite consisting of graphene and transition metal hydroxides for construction of nonenzymatic electrochemical sensor of nitrite detection.…”

An efficient non‐noble metal eletrocatalyst, nickel hydroxide/reduced graphene oxide nanocomposite (Ni(OH)2/sr‐GO), is synthesized in the absence of reductants and alkali by a simple one‐step solvothermal method. The morphology, structure, and composition of the Ni(OH)2/sr‐GO nanocomposite is characterized by various analytical techniques like scanning electron microscopy, X‐ray diffraction, Raman spectroscopy, X‐ray photoelectron spectroscopy, and energy dispersive X‐ray spectroscopy. The Ni(OH)2/sr‐GO nanocomposite is then used to construct a nonenzymatic amperometric sensor for highly sensitive detection of nitrite. The result shows that the Ni(OH)2/sr‐GO nanocomposite possesses superior electrocatalytic ability toward nitrite. The electrochemical performance of the Ni(OH)2/sr‐GO is evaluated by electrochemical impedance spectroscopy, chronocoulometry, and cyclic voltammetry. Under the optimal conditions, the electrochemical sensor for nitrite detection exhibits a linear range from 0.1 to 663.6 μM, with a detection limit of 0.07 μM (S/N=3). In addition, the sensor provides favorable selectivity, reproducibility, and stability, and can be successfully applied for the detection of nitrite in spiked water samples. Recoveries range between 95 and 108 %.

Novel nickel‐copper modified pencil graphite electrode (Ni−Cu/PGE) was fabricated and used as non‐enzymatic sensor for glucose determination. Ni and copper were electrodeposited on PGE using cyclic voltammetry. Morphology and composition of the modified PGE electrode were characterized by field‐emission gun scanning electron microscopy (FEG‐SEM), energy‐dispersive X‐ray spectroscopy (EDX) and Fourier transform infrared spectroscopy (FT‐IR). Electrochemical oxidation of glucose was evaluated by cyclic voltammetry as well as by amperometry. Electrochemical measurements indicate that the Ni−Cu/PGE exhibits a high sensitivity of 2951 μA mM−1 cm−2, and a low detection limit of 0.99 μM which are, respectively, three times higher and twice lower than that on Ni/PGE prepared in the same conditions. Moreover, Ni−Cu/PGE exhibits a wider linear range from 1 to 10000 μM with a rapid response time within 2 s. Moreover, Ni−Cu/PGE showed a remarkable stability. The electrode was successfully applied for determination of glucose concentration in human blood without significant interference from potential endogenic interferents. The good applicability of the elaborated sensor made Ni−Cu/PGE promising for the development of effective and inexpensive non‐enzymatic glucose sensor.
