摘要
本文在国家标准规范的基础上仔细探讨了水样预处理过程中的絮凝、过滤步骤对氨氮分析结果的影响,给广大实验操作者提供了一些比较明确的数据和结论,以使操作人员在实验分析中能清晰判断要预处理与否并对水样进行合理的预处理。
On the basis of national normative standard, this paper carefully discusses the influence to the effect of the ammonia-nitrogen analysis of the flocculation and filtration in the process of water sample pretreatment. This paper also provides anumber of comparatively specific data and conclusion, aiding operative workers to decide in focus whether it is necessary tocarry through pretreatment and to process reasonable pretreatment to the water sample.
