柱后反应-离子色谱法测定饮用水中的溴酸盐

Using Ion Chromatography with the Addition of a Postcolumn Reagent for Trace Bromate Analysis

该文对臭氧处理水过程中可能产生的无机消毒副产物溴酸盐的检测方法进行探讨,用柱后反应-离子色谱测定溴酸盐的方法,溴酸盐的定量浓度可以低至0.5μg/L,较以前文献[4]所测浓度2.0μg/L为低,降低了方法的检测限。该方法具有较好的灵敏度,准确度和较低的检测限,能满足欧盟水质标准的检测要求。

In this paper, Bromate in water was determined with Ion chromatography with the addition of a postcolumn reagent. Comparing with other method with no reagent addition, the results obtained showed that this method gives better linearity, stability, detection limit, accuracy and precision and can meet with the requirements of EC.
