摘要：

介绍了采用连续流动分析法,快速同时测定污水中总氮、氨氮、亚硝酸盐氮、硝酸盐氮的优化方案.在最佳实验条件下,质量控制样品测定值均在保证值范围内,样品回收率为96.0%～104.0%,RSD>2%.

关键词: 连续流动分析法, 总氮, 氨氮, 亚硝酸盐氮, 硝酸盐氮

Abstract:

The optimum program of determining the total nitrogen, ammonium-nitrogen, nitrite-nitrogen and nitrate-nitrogen in wastewater rapidly and simultaneous by continuous fluxion analysis is introduced.Excellent linear relationship has been observed after being tested through experiments under optimum conditions.The determination values of the quality controlled samples are all in guaranteed limits.The recovery rate is 96.0%-104.0%,and RSD＜2%.

Key words: continuous fluxion analysis, total nitrogen, ammonia-nitrogen, nitrite-nitrogen, nitrate-nitrogen
