Flow injection kinetic spectrophotometric method for the determination of trace amounts of nitrite

Single Step Synthesis of MoSe2−MoO3 Heterostructure for Highly Sensitive Amperometric Detection of Nitrite in Water Samples of Industrial Areas

“…Thus, the detrimental effect of nitrite on environment and human health makes its monitoring of utmost importance in public health and food industries. Although various analytical methods like spectrophotometry , chemiluminescence , capillary electrophoresis and chromatography have been developed for determination of nitrite, electrochemical methods gained wide attention due to their portability, low‐cost, specificity and sensitivity in real‐time analysis. In addition, electrochemical methods do not require any expensive instruments with time‐consuming and laborious procedures.…”

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

“…Due to these facts a development of a fast, simple, cost-effective, selective and sensitive method for its quantification is very important. Numerous methods have been reported in the literature dealing with nitrites quantification, such as spectrophotometric methods [10,11], flow methods [12], chemiluminescence [13] as well as electroanalytical methods [4,[14][15][16][17][18][19][20][21][22].…”

Determination of trace nitrite in pickled food with a nano-composite electrode by electrodepositing ZnO and Pt nanoparticles on MWCNTs substrate

“…Therefore, it is very important to carry out quantitative determination of nitrite in food and related environment fields. Up till now, many methods have been reported for the detection of nitrite, such as continuous flow analytical methods (Nouroozi & Mirshafian, 2009), spectrophotometry (Pourreza, Fat'hi, & Hatami, 2012;Rinc on, Martínez, P erez-Olmos, & Berzosa, 2008), colorimetry (Zhang et al, 2014), fluorometry (Jiao et al, 2004;Ohta, Arai, & Takitani, 1986), chemiluminescence (Doerr, Fox, Lakritz, & Fiddler, 1981), polarography (Yilmaz & Somer, 2008), chromatography (Butt, Riaz, & Iqbal, 2001;Wang, Wang, & Zhu, 2012), capillary electrophoresis (Betta, Vitali, Fett, & Costa, 2014), and gas chromatographyemass spectrometry (Akyüz & Ata, 2009), etc. However, those methods were costly, timeconsuming with complicated operations and strictly controlled reaction conditions, which limited their applications.…”
