Objective:To develop an ion chromatography method for the simultaneous determination of bromate,chlorate,and chlorite in water.Method:IonPac AS 19 chromatographic column,KOH automatic eluent generation device,mobile phase flow rate of 1.0 mL/min,500 μL bulk injection,conductivity detection cell temperature 40 ℃,chromatographic column temperature 30 ℃,suppressor current 87 mA.Results:Bromate at 0～100.0 μg/L,chlorate,Chlorite at 0～1000.0 μg/L,the concentration range has good linearity,The relative standard deviation is 0.10％～0.55％,and the average recovery rate in the spiked recovery test is 93.1％～104.9％.Conclusion:The method is simple,sensitive,and stable,and suitable for the simultaneous determina-tion of bromate,chlorate,and chlorite in drinking water.
