| Abstract: | Objective To probe into the availability of nitrite and nitrate determination in foods by ion chromatography. Methods To ascertain the most optimal conditions by experiment analysis. Results The precisions of nitrite and nitrate were 0.42% and 0.36% respectively, the coefficient of recovery of nitrite and nitrate were 96.8-100.7% and 98.4-101.8% respectively. Condusion Good selectivity, high sensitivity and high accuracy are advanced characteristics of this method. |
