摘要
氨氮自动监测仪可自动连续监测各类水体中的氨氮浓度,其准确性关系到水环境质量及水环境管理决策.当采用不同浓度的标准溶液对氨氮自动监测仪的示值误差的检定时,依据本不确定度评定方法进行评定可以获得不同浓度下氨氮自动监测仪的示值误差测量不确定度.可为为计量和环境监测领域氨氮自动检测仪的准确可靠,量值统一提供评价依据.
Ammonia-nitrogen is one of the most important parameters in the standards of water quality and waste water discharge. Ammonia-nitrogen automatic analyzer （ANAA） can be used to continuously determine the concentration of ammonia-nitrogen, and is the most popular method for online environmental monitoring. The accuracy of ANAA has significant meaning on water quality and corresponding decision-making. This paper discussed the evaluation of uncertainty for the result of ANAA indication error measurement. Resuhs obtained in this paper provides the evaluation basis for the reliable of ANAA in the areas of environmental monitoring and metrology.
