铬酸钡分光光度法与离子色谱法测定生活饮用水中硫酸盐的比较

摘要

为比较铬酸钡分光光度法与离子色谱法测定水中硫酸盐是否存在显著性差异,分别使用两种方法测定淮安市两个集中式生活饮用水水源地的地表水中的硫酸盐含量。其结果显示,两种方法的精密度、准确度和测定结果无显著性差异,均可作为测定生活饮用水中硫酸盐的方法。%To compare the Barium chromate spectrophotometry and Ion Chromatography method for determination of Sulfate,we collected 4 surface-water samples from 2 areas in drinking water of Huaian and detected he fluoride content.The results indicated that there not distinctive differences in the precision,accuracy and determination results of Barium chromate spectrophotometry and Ion Chromatography method.So Sulfate content in drinking water could be determined by the two method.
