Determination and Relationship of Ammonia Nitrogen, Nitrite Nitrogen, Nitrate Nitrogen and Total Nitrogen in Upstream Reservoir Water

摘要: 采用紫外分光光度法测定上游水库固定监测点位近两年采集样品的总氮、硝酸盐氮、氨氮、亚硝酸盐氮含量. 对测试结果进行分析比较, 探讨了上游水库水中总氮、硝酸盐氮、氨氮、亚硝酸盐氮的关系, 从而为上游水库水质数据分析和综合评价提供一定参考.

Abstract: The total nitrogen, nitrate nitrogen, ammonia nitrogen, and nitrite nitrogen in the upstream reservoir water were determined by the spectrophotometry. The contents of total nitrogen, nitrate nitrogen, ammonia nitrogen, and nitrite nitrogen in the samples collected from the fixed monitoring point of the upstream reservoir in recent two years were determined using the ultraviolet spectrophotometry. The test results were analyzed and compared, and the relationships among the total nitrogen, nitrate nitrogen, ammonia nitrogen, and nitrite nitrogen in the upstream reservoir water were discussed, thus a certain reference for the data analysis and comprehensive evaluation of water quality data in upstream reservoirs is provided.
