摘要: 建立了化妆品中溴酸盐的柱后衍生-离子色谱检测方法。采用ICS1100离子色谱仪,IonPac AS19色谱柱,以KOH为淋洗液洗脱,经衍生试剂衍生后以二极管阵列检测器对样品中溴酸盐含量进行检测。结果表明:该方法在1.25~125 μg/L 质量浓度范围内线性关系良好(R2=1);加标回收率为98%~100%,相对标准偏差约为1%,检出限为15.7 μg/kg,定量下限为51.9 μg/kg。方法快速、准确,选择性及灵敏度好,完全满足化妆品中溴酸盐检测的要求。

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
