“…The experimental conditions and analytical performances of different chemically modified electrodes relevant to graphene materials for the determination of nitrite are compared in Table S2. It is clear that the NrGO-modified GCE showed a relatively wide linear concentration range and a relatively low detection limit in comparison to most of the reported nitrite electrochemical sensors [14][15][16][17][18][19][20][21][22][23][24]. The lower detection limits reported in the literature were usually accompanied with narrower concentration ranges, and the higher upper limits of detectable concentrations reported in the literature were usually associated with higher detection limits.…”

“…The NrGO nanosheets exhibited a good electrocatalytic activity toward oxidation of nitrite at a relatively low oxidation potential (0.68 V). The newly fabricated nitrite sensor showed a wide linear concentration range (0.5-5000 μM) and a low detection limit (0.2 μM) even in comparison to the rGO-based electrochemical sensors mentioned above [14][15][16][17][18][19][20][21][22][23][24], as well as satisfactory selectivity, stability, and reproducibility. The developed electrochemical sensor was further applied for the determination of nitrite in pickled garlic and river water.…”

“…There are several techniques developed for quantitative determination of nitrite. For instance, capillary electrophoresis [6], ionic liquid dispersive liquid-liquid microextraction high-performance liquid chromatography (IL-DLLME-HPLC) [7], ion chromatography [8], chemiluminescence [9], fluorescent probe [10] and electrochemical method [11]. By comparison, electrochemical method is a kind of cheap and gleaming method because of its intrinsic sensitivity, high selectivity, fast analysis, simplicity [12] and environment-friendly [13,14].…”
