A novel and highly sensitive flow-injection chemiluminescence method for the determination of potassium bromate (KBrO3) has been developed. This method is based on the luminescence properties of the KBrO3-Na2SO3-quinine sulfate system in acid medium. Optimized experimental conditions and a possible mechanism were investigated. The relative chemiluminescence intensity responded linearly to the concentration of KBrO3 in the range of 7.054 x 10(-6)-1.008 x 10(-4) mol/L with a detection limit of 2.116 x 10(-6) mol/L. The relative standard deviation (RSD) at 5.0 x 10(-5) mol/L KBrO3 (n = 12) was 2.3%. The proposed method was applied successfully to the determination of KBrO3 in flour. (C) 2015 Elsevier Ltd.
