“…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.…”
