Abstract：Objective To establish a method for the determination of BrO3-,NO2-,NO3- in cooked meat products. Meth-ods The samples were prepared by ultrasonic extraction and purified with cation exchange resin column,then seperated by IonPac AS19 column. ASRS 300 4-mm anion inhibitor and conductivity detector were used. Standard curve method was used for quantitative analysis. Results The calibration curves had good linearity within 0. 1~5. 0 mg·L-1 ,r﹥0. 999. The limits of detection were 0. 5,0. 2,0. 2 mg·kg-1 and the limits of quantitation were 1. 5,0. 6,0. 6 mg·kg-1 for BrO3-,NO2-,NO3-. The recoveries of each anion were 83. 2% ~88. 7%,82. 0% ~88. 1%,78. 6% ~81. 0%,respectively. Conclusion The method was simple,sensitivity,and can be used to analyze three anions in cooked meat products.
