摘要
文章就斗门自来水公司需要选择测定水样中硫酸盐浓度的方法进行了比较研究,比较对象为铬酸钡分光光度法的冷热两种方法。通过比较研究表明,铬酸钡分光光度冷法操作较热法简单,并且在测定含低浓度的硫酸盐的水样时,精密度也比热法高。该项研究有助于斗门自来水公司做出选择铬酸钡分光光度冷法作为测试水样中硫酸盐浓度方法的决策。
To help Doumen Water Company to choose the assay of lcsting concentration of sulfate in watcr, a comparison research was held to compare cold one and thermal one of barium chromate spectrophotometry method. By comparing the results of the experiments, it showed that the cold method was relatively simpler than thermal one, and was more accurate when it was used in testing the water which had sulfate in low concentration. Since that, it was better for Doumen Water Company to use the cold method.
