Research ArticleOpen accessIn the keywordsSimultaneous Detection of Nitrite and Nitrate in Celeries and CarrotsDongwu Liu, Jinye Niu, Ling Kong, Zhiwei ChenIn this study, the anions nitrite ion (NO2-) and nitrate ion (NO3-) in celeries and carrots were detected with the technique of ion chromatography. A Dionex ICS-2000 ion chromatograph was used to detect the content of NO2- and NO3- in celeries and carrots. NO2- and NO3- were separated on a DIONEX Ionpac AS19 A-4 mm ion-exchange column and an Iopac … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 14 May 2016 · 7,214 accessesView PDFCite
