离子色谱法同时测定饮用水中的IO_3^-,ClO_2^-,BrO_3^-和NO_2^-

Study on The Ion Chromatographic Determination of IO_3^-,ClO_2^-,BrO_3^- and NO_2^- in Drinking Water

采用离子色谱法可同时测定饮用水中IO3-,ClO2-,BrO3-和NO2-的含量,最低检测限分别为0.30μg/L,0.22μg/L,0.05μg/L和0.89μg/L,回收率为91%～107%,相对标准偏差均<3%。实验证明该法快速、适用、准确、灵敏度高。

the ion chromatography method can be used to detect the contents of IO3^-, ClO2^-, BrO3^- and NO2^- in drinking water simultaneously, the lowest limits of detection are 0.30 μg/L,0.22 μg/L,0.05 μg/L and 0.89 μg/L respectively, the recovery rate is 91% - 107%, and the relative standard deviation isles than 3%. The experimental results show that this method has the advantages of high speed, high applicability, high accuracy and high sensitivity.
