Abstract

In 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 AG AS19 A-4 mm guard column. The eluant was suppressed with an anion electrical self-regenerating suppressor (ASRS 300) and the content of NO2- and NO3- was detected with a conductivity detector. The detection limits were obtained for anions NO2- and NO3-. The present results showed that the ion chromatography was a suitable technique for the simultaneous determination of NO2- and NO3- in vegetables.
