| 摘 要： | 用改进后的二苯碳酰二肼分光光度法测定水样中六价铬，样品显色时只加入1ml1＋1硫酸与2ml显色剂（1）。与原方法相比，简化分析步骤，提高分析速度，精密度和准确度都得到很好的保证。

| Abstract: | The hexavalent chromium in water is determined with improved dibenzoyl, when the sample appears color, 1 ml sulfuric acid and 2 ml color agent are added. Compared with organic method, the analysis procedure is simplified, analysis speed is raised and precision and accuracy are guaranteed well. |
