摘要
提出了不同水质样品的处理方法，采用流动注射碱性过硫酸盐紫外氧化方法在线测定水中的总氮，线性范围为200—2000μg／L，检出限为5．6μg／L，加标回收率为95．4％-102％。该方法与标准方法测定结果无显著性差异。
Total nitrogen in water and wastewater was determined by using flow injection online alkaline persulfate/UV digestion. The disposal method for different water sample were put forward. Linear range was 200 -2000 μg/L, the detection limit was 5.6 μg/L, and the recoveries were 95.4% - 102%.
