摘　　要：总氮,作为水质监测的基础指标,是衡量水体污染程度、自净状况和水体富营养化的重要指标,对于评估水体质量和保护生态环境具有重要意义。本文使用紫外消解分光光度法检测水中总氮对检测过程中的主要影响因素进行探讨,通过对样品自身影响因素、消解过程控制、试剂药品提纯等方法对检测过程进行优化,有效地解决了实验空白过高的问题,提高了检测的可靠性和准确性。Total nitrogen,as a fundamental indicator for water quality monitoring,is an important indicator for measuring the degree of water pollution,self purification status,and eutrophication.It is of great significance for evaluating water quality and protecting the ecological environment.This article explores the main factors affecting the detection process of total nitrogen in water using ultraviolet digestion spectrophotometry.By optimizing the detection process through methods such as sample self influencing factors,digestion process control,and reagent and drug purification,the problem of high experimental blank has been effectively solved,and the reliability and accuracy of the detection have been improved.
