| 摘 要： | 在标准重铬酸钾法中，提出用MnSO4-NiSO4组合催化剂取代Ag2SO4催化剂，快速测定废水的CODcr。其最佳实验条件为质量之比MnSO4:NiSO4=1:1.5，MnSO4-NiSO4总量为0．15g,加热回流时间为5min。通过对8种不同浓度的标准邻苯二钾酸氢钾样品和5种废水样分析，经统计检验表明，本方法与标准重铬酸钾法无显著性差异，两者具有较好的可比性。

| Abstract: | A method for determination of CODCr in waste-water without Ag2SO4has been proposed. The optimal experimental conditions were as follows: Weight ratio of MnSO4:NiSO4 was 1:1.5, and the total weight was 0.2g, reflux time was 5 minutes. 13 water samples have been analyzed with this method, and compared with the standard potassium dichromate method. The result showed that there were no different between them. |
