摘要
建立一种同时快速测定饮用水中F-、Cl-、NO2-、NO3-、SO42-5种阴离子及Cl O2-、Br O3-、Cl O3-3种消毒副产物的离子色谱方法。测定中采用Metrohm A Supp 5 250+A Supp 1 Guard组合分离柱对上述5种阴离子及3种消毒副产物进行分离。试验结果表明,该方法相关性好、精密度高、无干扰、操作简单、分析速度快。
A rapid method was established for simultaneous determination of five anions（F^-、Cl^-、NO2^-、NO3^-、SO4^2-） and three disinfected by-products（Cl O2^-、 BrO3^-、 ClO3^-） in drinking water by ion chromatography.Metrohm A Supp 5 250＋A Supp 1 Guard were used to separate the five anions and three by-products. Results showed this method has good correlation, high sensitivity, non-interference, easy to operate, and high detection speed.
