碱性过硫酸钾消化法测定高藻水中总氮相关问题探讨

The Determination of Total Nitrogen in High Cyanobacteria Water by Alkaline Persulfate Potassium Digestion Method

摘要: 富营养化水体中藻类大量繁殖形成的高藻水，对水体生态环境、人体健康、公共卫生安全等方面均构成严重威胁。高藻水的处理工艺以及水质检测为近年来的研究热点，本文在利用碱性过硫酸钾氧化-紫外分光光度法(参考国标法)测定高藻水中总氮的研究过程中，在使用比色管方法上、消化时长和消化温度、过硫酸钾纯度等方面对空白值的影响进行探究，并对实验方法进行优化。与此同时，利用优化后的方法对高藻水进行测定，提出一种准确测量高藻水中总氮含量的方法。

Abstract: The high cyanobacteria water produced by the cyanobacteria bloom in eutrophic water poses a serious threat to the ecological environment, human health, and public health security. The high cyanobacteria water treatment process and water quality detection are the research hotspots in recent years. In the study of the use of alkaline potassium persulfate oxidation-ultraviolet spec-trophotometry to determine total nitrogen in high algae water, the use of colorimetric tubes, di-gestion time, the effects of digestion temperature and potassium persulfate purity on blank values were explored, and experimental methods were optimized. At the same time, an optimized method was used to measure high algae water and a method for accurately measuring total nitrogen content in high cyanobacteria water was proposed.
