| 摘 要： | 经实验证明,用碱性过硫酸钾氧化-紫外分光光度法测定水样中的总N,以一次蒸馏水代替重蒸馏无氨水,既减少了实验操作程序,又不影响测定结果,同时本文确定了最佳实验条件,并对标准样品进行分析,结果理想。

| Abstract: | The experimental procedure were predigested under the condition that did not effect the experimental results by using alkal potassium persulphate oxidation-ultraviolet spectrophotometry to determine the total nitrogen in water sample with first water instead of redistillation non-ammonia water.The best conditions were obtained,and the results were satisfied. |

| Keywords: | alkal potassium persulphate oxidation total nitrogen ultraviolet spectrophotometry |
