本研究的目的是对这些溴酸盐方法进行综合比较，评估改良的选择性阴离子浓度法与EPA方法300.1和新的柱后法的性能。方法300.1只有有限的性能数据可用，其他两种方法没有性能数据报告。EPA在ICR的三个月期间收到的市政原水和成品水样本，涵盖了ICR参与者提交的所有相关水类型，使用三种方法进行分析。 对这些方法进行了评估，以备将来用于合规性监测，并报告了各自的优缺点。

The objective of this study was to conduct a comprehensive comparison of these bromate methods, evaluating the performance of the modified selective anion concentration method to EPA Method 300.1 and the new postcolumn method. Only limited performance data has been available for Method 300.1 and no performance data has been reported for the other two methods. Municipal raw and finished water samples received by EPA over a 3 month segment of the ICR, spanning all relevant water types submitted by the ICR participants were analyzed using the three methods. The methods were evaluated for future use in compliance monitoring and their individual strengths and weaknesses reported.
