摘要
总氮是水质检测的一个重要指标,但是测定过程复杂且容易引入误差。本文主要从水样预处理、消解以及测定方法等方面分析比较了测定地表水中总氮指标的五种方法,总结出了每种测定方法的异同与优劣,对于总氮测定方法具有一定的指导意义。
Total nitrogen is an important indicator of water quality testing,but the measurement process is complex and easy to introduce errors.In this paper,five methods for determining the total nitrogen index in surface water are analyzed,and compared from the aspects of water sample pretreatment,digestion and determination methods.The similarities and differences of each method are summarized,which has certain guiding significance for the determination of total nitrogen.
