Abstract: A detection method for determination of bromate salt content in cosmetics with ion chromatography together with post-column derivation was established.The sample is separated on ICS 1100 ion chromatography system equipped with IonPac AS19 column,using KOH as eluent,with photodiode array as the detector.Results showed that good linearity appears in the range of 1.25-125 μg/L with correlation coefficient of R2=1.The spiked recoveries are in the range of 98%-100%,with relative standard deviation as about 1%,limit of detection as 15.7 μg/kg and limit of determination as 51.9 μg/kg.With advantages of simplicity,good reproducibility and high sensitivity,the method is suitable for the determination of bromate salt in cosmetics.

Key words: cosmetics, bromate, post-column deriviation-ion chromatography
